    To solve using substitution, you need to sub the first equation into the second one.

    So, the new equation would be:

    -4 + 5 (3x - 14) = - 37

    Then, you just distribute the 5 and solve. Your answer should be x = 7.4.

    To find the y, sub the newly found x into one of the original equations. For example, the first.

    y = 3 (7.4) - 14

    y = 8.2

    Therefore, x = 7.4 and y = 8.2.
