Answer:
4x -9
Step-by-step explanation:
First, expand it by multiplying (x+4) with -2.
(x + 3) - 2(4 + x) + 5x - 4
= x + 3 - 8 - 2x + 5x - 4
Then, collect like terms. Add up the coefficient of x, and the whole numbers separately.
= x - 2x +5x + 3 -8 -4
= 4x -9
When nothing can further be simplified, you get the answer.
