5th grade math

T = t-shirts & S = shorts

T + T + S + S = $42
T + S + S + S = $45


asked by Leann
  1. 2T + 2S = 42

    Divide both sides by 2.

    T + S = 21

    T + 3S = 45

    Subtract second equation from the first.

    2S = 24

    Divide both sides by 2.

    S = 12

    You should be able to work it from here.
