    In this question, you're solving for a.

    Solve for a:

    -8 (1 - a) = -7 - (1 - 3a)

    use the distributive property

    -8 + 8a = - 7 - (1 - 3a)

    -8 + 8a = - 7 - 1 + 3a

    combine like terms

    -8 + 8a = - 8 + 3a

    subtract 3a from both sides

    -8 + 5a = - 8

    add 8 to both sides

    5a = 0

    divide both sides by 5

    a = 0
