To simplify the expression (43 + 7w - 15 - 5w), first combine like terms. Start by combining the constant terms: (43 - 15) which equals (28). Next, combine the (w) terms: (7w - 5w) which equals (2w). Therefore, the simplified expression is (28 + 2w).

28*21 equals 84
4w - 2 = -7w11w - 2 = 011w = 2w = 2/11
4 times 21 equals 84.
13,440 divided by 160 equals 84.
