    Solve for x:5 x + 3 (x + 4) = - 20

    3 (x + 4) = 3 x + 12:3 x + 12 + 5 x = - 20

    Grouping like terms, 5 x + 3 x + 12 = (5 x + 3 x) + 12: (5 x + 3 x) + 12 = - 20

    5 x + 3 x = 8 x:8 x + 12 = - 20

    Subtract 12 from both sides:8 x + (12 - 12) = - 12 - 20

    12 - 12 = 0:8 x = - 20 - 12

    -20 - 12 = - 32:8 x = - 32

    Divide both sides of 8 x = - 32 by 8: (8 x) / 8 = (-32) / 8

    8/8 = 1:x = (-32) / 8

    The gcd of - 32 and 8 is 8, so (-32) / 8 = (8 (-4)) / (8*1) = 8/8*-4 = - 4:Answer: x = - 4
