    Let's say that mom is \(m\) years old, then Minya will be \(m - 30\). We know:\[ m + (m - 30) = 58 \]Solve for \(m - 30\).

    can you first solve the equation?

    Okay if it is m-30 = 58 then you would do the inverse of it which would be 58 - 30 = 28.

    \[ m - 30 = 58\]\[ m = 58 + 30\]

    58 - 30 = 28

    \[2m = 88 \implies m = 44 \implies m - 30 = 14 \]
