OK, do not fear-cattbarf is here. Since you have an equation with a "1y" term, use it. 4x-7* (5-3x) = 5. Expand, collect terms, and solve for x. Then solve either (or preferably both equations) for y.

The first step that we do is to either solve for x or y 3x+y=5 I will solve for y Y= 5-3x we just moved the 3x to the right next we plug in the y in the next equation 4x-7(5-3x)=-10 dist. the 7 4x-35+21x=-10 combine the x 25x-35=-10 move the 35 25x=-10+35 do the math 25x=25 divide by 25 x=1 to check plug the x and y into the equations and make sure they equal the answers

3x+y=5
y=5-3x
4x-7(5-3x)=-10
4x-35+21x=-10
25x=-10+35
25x=25
x=25/15=1
y=5-3*1=5-3=2
