    n = 4 4/5

    or, in decimal form:

    n = 4.8

    Step-by-step explanation:

    3n - 15 = 7 - 2n + 2

    3n + 2n = 7 + 2 + 15

    5n = 24

    n = 4 4/5

    n = 4.8

    n = 4

    Step-by-step explanation:

    3 multiplied by n is 3n.

    3 multiplied by - 5 is - 15.

    so 3n-15 = 7-2 (n+1)

    7-2 (n+1) is - 2 multiplied by n is - 2n and - 2 multiplied by 1 is - 2.

    3n-15=7-2n-2

    then move the variables to one side and numbers to the one side.

    3n+2n=15+7-2

    *If you are moving across the equation the symbols change. Like negative to positive. Division to multiplication.

    so 5n=22-2

    5n=20

    5 multiplied by 4 is 20 so n is going to be 4.

    N=4
