    x/100 + 6/100 + 75/100 =1

    x/100 + 81/100 = 100/100

    x/90-10/90-4/90-2/90=1

    x/90-4/90=90/90
    x=86

    what about this one

    You're on the right track and close. However, you missed -2/90 in the original problem.

    3/19-1/19+7/19+x/19=1
    x=19-3+1+7
    x=16+8
    x=24

    In this problem, 19 is the denominator. When adding and subtracting fractions with the same denominator, only add or subtract the numerators.
