Question

How do you simplify an expression like -3x + 15 - 8x? do you combine like terms and if so, how?​

Answer 1

so, with terms like -3x and -8x remember to keep the negative or positive sign the same when combining like terms.

in this instance the simplified expression would be:

15 - 11x

because -3x - 8x = -11x

does this make sense? lmk if u need help
