    Martha is 18 years older than Harry. Their ages add to 106. Write an equation and solve it to find the ages of Martha and Harry.

    Let m be Martha's age. Let h be Harry's age. We're given two equations:
    1. m = h + 18 (older means we add)
    2. h + m = 106
    Substitute equation (1) into equation (2) for m:
    h + h + 18 = 106

    To solve for h, we type this equation into our search engine and we get:
    h = 44
