    30-f+8f=30

    30+7f=30

    Move + 30 to the right side. Sign changes from + 30 to - 30.

    30-30+7f=30-30

    7f=0

    Divde by 7

    7f/7=0/7

    Cross out 7 and 7, divide by 7. Becomes 1*1*f=f

    f=0

    Answer: f=0

    f=0

    Step-by-step explanation:

    30-f+8f=30

    30+7f=30 (combine like terms, in this case - f stands for - 1 so (-1+8=7))

    7f=0 (divide by 7)

    f=0 (any number divided by 0 is 0)
