Question

3x - 3y = 12 4y - 8x = -16

Answer 1

For the first one 3x - 3y what do you think your supposed to do first?

Answer 2

I have to walk you through this.

Answer 3

Determine the solution to the system and check your solution in both equations. Input the solution to the system, putting the solution in ordered pair (x, y) form.

Answer 4

Ok so the first step is add 3y to both sides.

Answer 5

Now what do you get when you do that?

Answer 6

Hello?

Answer 7

3x-3y=12
3x=12+3y
x=(12+3y)/3 substitute this in the equation 4y-8x=-16
4y-8(12+3y)/3=-16
4y-(96/3)-(24y/3)=-16
4y-32-8y=-16
-4y=-16+32
-4y=16
y=-16/4
y=-4
x=(12-12)/3=0
