So you add like terms (3x+2x=5x)
1.5xy=10
then you get y by itself
1.y=10/5x
for 2 you have to bring x to the other side.
2.-3/4y=6-1/3x --> then divide
y=-8+4/9
solve for y:
1. 3x+2xy=10
2. 1/3x-3/4y=6

u have to: 3x + 2xy = 10
(-3x) + 3x + 2xy = 10 - 3x
2xy = 10 - 3x
divide by 2x: 2xy/2x = 10/2x - 3x/2x
answer y = 5x - 1.5
(-3x) + 3x + 2xy = 10 - 3x
2xy = 10 - 3x
divide by 2x: 2xy/2x = 10/2x - 3x/2x
answer y = 5x - 1.5
