Notice that the questions specifies that you should expand and simplify. This means expanding the equations is a good idea. To expand the equation, we will start by expanding each brackets.

3(x-2)-...

To find the answer to this, we can use the point-slope form. To do this: y - (-7) = 3 (x - 4) Simplified: y + 7 = 3x - 12 : y = 3x - 19

30y+15x=120

12y+15x=84

18y=36

y=2

4(2)+5x=28

8+5x=28

5x=20

x=4
