Question 689964: I need help with this problem.
Solve the following system of equations, using the elimination method:
4x + 3y = -4
3x - 7y = 34
Answer by Stitch(470) (Show Source): You can put this solution on YOUR website!
Given: &
Set both equations equal to zero
&
Multiply the first equation by 3

Multiply the second equation by 4

We did that multiplication to get the X variables to a common number (12)
Since both equations equal zero, we can set them equal to each other

Subtract 12X from both sides

Add 28Y to both sides

Subtract 12 from both sides

Divide both sides by 37

-----------------------
Now plug -4 into one of the given equations for Y

Add 12 to both sides

Divide both sides by 4
