    20.

    m = - 52

    22.

    x=13

    24.

    a=-90

    26.

    n=-2

    28.

    a=9

    30.

    m=-10

    Step-by-step explanation:

    20. m/4=-13

    m = - 13*4 = - 52

    22. - 143=-11x

    x=-143/-11 = 13

    24. - 5=a/18

    a=-5*18 = - 90

    26. n-8=-10

    n=--10+8

    n=-2

    28. a+11=20

    a=20-11

    a=9

    30. 18+m=8

    m=8-18

    m=-10
