(-2x + 3) - (3x + 2)
= -2x + 3 - 3x - 2
= -5x + 1

well when you do the math and put like terms together its
-2x-3x + 3-2
=-5x-1
maybe your looking at the wrong question cuz thats as simple as that gets
if what your reading is write your answer would be 10x+15 and theres no way u can get that from eachother

That answer given in the book is incorrect for simplifying this expression.
you need to distribute that negative sign into the second set of parentises...So (-2x + 3) - (3x + 2)...becomes...-2x + 3 - 3x - 2
The answer is -5x + 1

= -2x + 3 - 3x - 2 = -5x + 1

The answer is -5x + 1, there is obviously an error in the book...unless you copyed the question incorrectly.
