n (number) minus four ----->n-4
2 x 4 - x = 7x
The expression simplifies to: -7x-4
H + 88 - 4 which can be simplified to H + 84.
(35 - 16)/4 = 19/4

Imagine the number line. Suppose on the left it starts -6, -5, -4, -3, -2, -1, 0, +1, +2, +3, etc. Let's calculate 2 x (-3). The expression -3 says starting at zero, go left 3 steps. The expression 2 x means do it twice. Where do you finish? -6 If you see why you finish on the left side, you have your answer. What about minus x minus. Let's calculate (-2) x (-3). Again -3 says starting at zero go left 3 steps. The expression -2 x means, no, go the other way instead -- twice. Where do you finish? +6. Minus x minus = plus.
4*(x - 8)

3x+6=8x-4 by the way x=2
