    -12 = 4 (n-2)

    multiply 4 with what's in the parentheses. You want to distribute it.

    You get

    -12 = 4n - 8

    move the constant (-12) to the opposite side of the =.

    move the variable (4n) to the left, or opposite side of the =.

    equation now looks like

    -4n = - 8+12

    Calculate the sum or difference of - 8 + 12

    -4n=4

    divide by negative four on each side

    n = - 1
