Answer:


Step-by-step explanation:

First solve -5x+9y=-12 for x:


-5x+9y=-12

-5x+9y-9y=-12-9y

-5x=-12-9

-5x=-9-12

-5x/-5=-9/5-12/-5

x=9/5y+12/6


Substitute x into an equation


3(-9/5y+12/6)+2y=22

37/5y+36/5=22

37/5y+36/5-36/5=22-36/5

37/5y=74/5

37/5y/37/5=74/5/37/5

y=2


Substitute y in x=-9/5y+12/6


9/5(2)+12/6

x=6


Solution Set: (6,2)
