    1. correct
    2.correct.
    3.

    x=4(90-x) will give you an answer of greater part, and you need other part too

    separate 90 in 2 parts so that one part is 4 times the other part
    so, let one part be x, then we know that the other part is 4x

    then
    90=x+4x
    5x=90
    x=18->one part
    the other part is 4x=4*18=72

    =>90=18+72

    4. correct
    5. correct
