  1. Let L stand for the larger and S stand for the smaller.

    From the second sentence, you know that L = S + 20.

    From the second sentence, you know

    4L = 5S + 70

    Substitute S + 20 for L in the second equation. Solve for S. Put value of S in the first equation to solve for L. Check answers by putting both values in the second equation.

    I hope this helps. Thanks for asking.
