Step by Step Explanation: 1st Equation: since "solve" usually means to find x unless told to solve for another variable, we are going to isolate x in both equations
-24-8x=12y (add 24 to both sides) +24 +24
-8x=12y+24 (isolate 8 from x) /-8 /-8
x=-3/2y-3 [simplify fractions (-12/8 turns to -3/2)]
2nd Equation: 1+10/18y=-7/18x
1+10/18y=-7/18x (convert 5/9 to 10/18 to divide)
1+10/18y=-7/18x (isolate -7/18 from x) /-7/18 /-7/18
(to make this easier on ourselves) -(10y+18)/7=x OR -18/7-10/7y=x
