5x + 4y = - 37

5x + 4y-4y = - 37 -4y

5x=- 37 -4y

5x/5=- 37/5 -4y/5

x=-7.4-.8y

3x - 4y = - 35

3(-7.4-.8y) - 4y = - 35

3(-7.4) (3)(-.8y) - 4y = - 35

-22.2-2.4y-4y=-35

-22.2-6.4y=-35

-22.2-6.4y+22.2=-35+22.2

-6.4y=-12.8

-6.4y/-6.4=-12.8/-6.4

y=2

x=-7.4-.8y

x=-7.4-.8(2)

x=-7.4-1.6

x=-9
