    -5 (n-1) = 7 (n+3)

    First, distribute the 5 in the first parentheses.

    -5n + 5 = 7 (n+3)

    Next, distribute the 7 in the second set of parentheses.

    -5n + 5 = 7n + 21

    Subtract 7n from both sides.

    -5n + 5 - 7n = 21

    Subtract 5 from both sides.

    -5n - 7n = 21 + 5

    Collect like terms.

    -12n = 16

    Divide both sides by - 12

    Answer - 3/4

    -3/4

    Step-by-step explanation:

    The First step is to distribute the 7 in the second part of parentheses.

    -5+5-7n=21

    -5-7n=21+5

    Then collect the terms

    -12n=16

    Lastly distribute both sides by - 12

    And the answer is - 3/4
