Question

Simplify (3x + 5) + (2x - 9) - (4x + 3). x - 7 -x - 7 -9x - 1 9x - 1

Answer 1

Hi Grant.

(3x + 5) + (2x - 9) is what we'll start with. Considering we cannot combine variables with numbers, we can only combine like-terms.

3x + 2x; 5 - 9; we result with: 5x - 4

Now, we are left with (5x - 4) - (4x + 3)
Remember to distribute the negative sign to everything to the right.

(5x - 4) - 4x - 3. We are now able to simplify and solve for our answer.

5x - 4x; -4 - 3; we result with x - 7.

Your answer is A.) x - 7.

I hope this helps!
