a bag has 57 blue and green marbles. there are 13 more blue marbles than green marbles. How many blue and green marbles are in the bag

  • math -

    green marbles --- x
    blue marbles ---- 57-x

    57-x - x = 13
    -2x = -44
    x = 22

    so 22 green and 35 blues

    check:
    do they add up to 57 ? YES
