Algebra 1 : How to find the solution to an equation

Possible Answers: Correct answer: Explanation: To solve for, you must first combine the 's on the right side of the equation. This will give you. Then, subtract and from both sides of the equation to get. Finally, divide both sides by to get the solution. Report an Error. We are given the following system of equations: We are to find and. We can solve this through the substitution method. First, substitute the second equation into the first equation to get. Solve for by adding 4x to both sides. Add 5 to both sides. Divide by 7. So. Use this value to find using one of the equations from our given system of equations. I think I'll use the first equation (can also use the .

A cube has a volume of. If what a wicked gang are we lyrics width isits length isand its height isfind. Since the object in question is a cube, each of its sides must be the same length. Therefore, to get a volume ofeach side must be equal to the cube root ofwhich is cm. We can then set each expression equal to. The first expression can be how to find solutions to an equation by either orbut the other two expressions make it evident that the solution is.

Solve the system for and. The most simple method for solving systems of equations is to transform one of the equations so it allows for the canceling out of a variable. In this case, we can multiply by to get. Then, we can add to this equation to yieldso. We can plug that value into either of the original equations; for example. So, as well. By solving one equation forand replacing in the other equation with that expression, you generate an equation of only 1 variable which can be readily solved.

Solve this system of equations for :. Multiply the top equation by :. To solve this system of equations, use substitution. First, convert the second equation to isolate. Then, substitute into the first equation for. Combine terms and solve for. Now that we know the value ofwe can solve for using our previous substitution equation. When we add the two equations, the and variables cancel leaving us with:.

Solve for :. First, combine like terms to get. Then, subtract 12 and from both sides to separate the integers from the 's to get. Finally, divide both sides by 3 to get. We are to find and. We can solve this through the substitution method. First, substitute the second equation into the first equation to get.

Solve for by adding 4x to both sides. Use this value to find using one of what is my body shape trinny and susannah equations from our given system of equations.

I think I'll use the first equation can also use the second equation. If you've found an issue finnd this question, please let us know.

Analyzing the number of solutions to linear equations

Practice telling whether an equation has one, zero, or infinite solutions. For example, how many solutions does the equation 8(3x+10)=28xx have? x^x^2+4=0. \sqrt {x-1}-x= \left|3x+1\right|=4. \log _2 (x+1)=\log _3 (27) 3^x=9^ {x+5} equation-calculator. en. Sign In. Sign in with Office More than just an online equation solver. Wolfram|Alpha is a great tool for finding polynomial roots and solving systems of equations. It also factors polynomials, plots polynomial solution sets and inequalities and more. Learn more about: Equation solving» Tips for .

Solve for :. Then, you can further simplify by adding 5 and to both sides to get. Then, you can divide both sides by 5 to get. What number is six less than eight more than one half of four times the square of the greatest negative integer? Remember to cancel as you go--the 18 will cancel with the 27, the 4 will cancel with the 8, and so on:. To solve for , you must first combine the 's on the right side of the equation. This will give you. Then, subtract and from both sides of the equation to get.

Finally, divide both sides by to get the solution. First, use the distributive property to simplify the right side of the equation:.

Then, subtract and add 4 to both sides to separate the 's and the integers to get. Divide both sides by 3 to get. To solve for , first divide both sides by :. Then, subtract both sides by to get.
