the original equation:
If y is marco's age and that is 38
38=x-3, then just solve for x
Again, if y is marco's age and that is 72
72=x-3, just solve for x

can someone solve it for me TT-TT
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.
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.
And you have:
And solve the other one in the same way.
