I'm having trouble with something. The topic question was fine because it only had 3 variables, 2 of which were given, so you just had to isolate the 3rd one and solve for it. But for this one, there's 4 variables; . You're asked to find the value for y' while given x and x'. How could I solve that? I have 2 unknown variables. (y' and y)
BTW; x = 8, x' = 10.
