A system of equations is shown below.

5x - 5y = 10
3x - 2y = 2

Part A: Create an equivalent system of equations by replacing one equation with the sum of that equation and a multiple of the other. Show the steps to do this.

The Solution to the original problem is:
x = -2
y = -4
part A:
5x-5y=10
(3x-2y=2) * 2

5x-5y=10
6x-4y=4
add:
11x-9y=14
New System:
11x-9y=14
3x-2y=2
Hope this helps!:)

Yes but why did you multiply the second equation by two and not the other? Do you not have to do the same to both equations?

anonymous · Answer

I just want to figure out how to do this myself to I'm not looking for anyone to give me answers.

yanasidlinskiy · Answer

Do you know how to solve the original equation?

anonymous · Answer

Which one? There are two in the original system.

yanasidlinskiy · Answer

Either one.

anonymous · Answer

I can find the solution of them both, by getting them into y=mx+b form and then graphing them right?
