the original equation: y=x3 If y is marco's age and that is 38 38=x3, then just solve for x Again, if y is marco's age and that is 72 72=x3, just solve for x

What you want is Rosa's age. The problem says x is Rosa's age. What you need to do is leave the x along on one side of the equation. From: 38=x3 Since you have negative 3 along with the x, just add +3 to eliminate it (because 3+3=0) BUT, in order for the equation to remain valid, add +3 to the other side of the equation too. So: 38+3=x3+3 And you have: 41=x And solve the other one in the same way.
