Answer is in the attachment below. Please open it up in a new window to see it in full.
Mary = 3x
Seth = X
If we know that Mary is three times older than Seth, we can set this up into an equation.
3x + x = 76
Now, we can simplify on the left side by adding the Xs together.
4x = 76
X = 19
Therefore, Seth is 19 years old and Mary is 57 years old.
