3x+2y=22
5x9y=25

first one times 9 > 27x + 18y =  198
2nd one times 2 > 10x  18y = 50
add them : 37x = 148
x = 4
I will let you finish it.

3x+2y=22 (1)
5x9y=25 (2)
Multiply (1) by 9 and (2) by 2 to get the y's to cancel
27x+18y=198 (3)
10x18y=50 (4)
Add (3) and (4) together
37x=148
Divide both sides by 37
x=4
Substitute that in either original equation (1) or (2) to solve for y. Check to make sure it works for the other equation, as well.
