    41-2n = - 5 (2n - 8)

    41-2n = - 10n + 40 (open brackets)

    take - 2n to other side and bring 40 in its place. (change of signs take place when bringing to other side of the equation)

    41-40 = - 10n+2n

    1 = - 8n

    n = - 1/8 (standard form)

    41-2n=-5 (2n-8)

    41-2n=-10n+40

    -2n+10n=40-41

    8n=-1

    1/8 (8n) = 1/8 (-1)

    n=-1/8
