    a. d=20

    b. f=0

    c. e=-7

    d. f=-1

    Step-by-step explanation:

    A. d+d+10=50

    2d+10=50

    Substrate 10 from both sides

    2d=40

    Divide both sides by 2

    d=20

    B. 30-f+8f=30

    30+7f=30

    Substrate both sides by 30

    7f=0

    Divide both sides by 7

    f=0

    C.-12=4e+23+e

    Collect like terms

    -12-23=4e+e

    -35=5e

    Divide both sides by 5

    e=-7

    D. 42=32-6f-4f

    Collect like terms

    42-32=-6f-4f

    10=-10f

    Divide both sides by 10

    F=-1

    Step-by-step explanation:

    a) d + d + 10 = 50

    2d + 10 = 50

    2d = 50 - 10

    2d = 40

    d = 40/2

    d = 20

    b) 30 - f + 8f = 30

    30 + 7f = 30

    7f = 30 - 30

    7f = 0

    f = 0

    c) - 12 = 4e + 23 + e

    -12 = 5e + 23

    5e + 23 = - 12

    5e = - 12 - 23

    5e = - 35

    e = - 35/5

    e = - 7

    d) 42 = 32 - 6f - 4f

    42 = 32 - 10f

    32 - 10f = 42

    -10f = 42 - 32

    -10f = 10

    f = 10/-10

    f = - 1
