Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)

19 (7x + 2) • (x + 1)
20 ax + 2ay - 5xb - 10
21 (x - 1) • (2x - 1)
22 (3x - 1) • (x + 5)
23 (12r + 11s) • (12r - 11s)
24 (7x - 9) • (x + 5)
