Jars, if you "see" that 5x + -4x = x, why can't you "see" that 2x + -4x = -2x ????jarrodj20 said:3 + 2x + -4x

this is what i think is the answer but i'm probably wrong:

3 + 2x + -4x

5x + -4x

1x

Answer is 3 - 2x

REMEMBER: 3 + 2x is NOT EQUAL to 5x :shock:

and

REMEMBER: pay attention in class :idea:
