accumulating like words (I discovered the term "combining" like words) would be 8x - 5x is 3x (8-5=3) dispensing has to do with the parenthases. So 2(4x+3) potential distinctive 2 by potential of all the climate interior the parentheses or 8x+6 (2x4 is 8 and 2x3 is 6). #4 -5x + 4(2x+2) = a million first distribute -5x + 8x + 8 = a million (4x2 is 8 for the two) them deliver at the same time (combine) 3x + 8 =a million (-5+8 is 3)

First get rid of the brackets.
2(x + 4) becomes 2x + 8
The whole expression becomes
2x + 8 - 5x + 7
collect like terms
2x - 5x + 8 + 7
now calculate
-3x + 15 or 15 - 3x
Simple
