-5x+3y=8 THAN X=9-10Y
-5(9-10y)+3y=8
-45-50y+3y=8
-47y=8 +45
-47y=53
y=-53/47


x=9-10y
x=9 - (10 * (-53/47))
x=9 + 530/47
x= (423 + 530 )/47
x= 953/47

Get y by itself so add 5x to both sides. It would equal 3y=5x+8. Divide both sides by 3 and you get y=5/3x+8/3. Then for the other get y by itself. Subtract 9 from both sides so you get -10y=x-9. Divide both sides by -10 which would equal y=-1/10x+9. I hope that's what you were meaning :)
