What is 4 (2-x) + 15=3 (x+3)

Answer: - 2

4 (2-x) + 15=3 (x+3)

=?

x=2

Step-by-step explanation:

Question: 4 (2-x) + 15=3 (x+3)

1) Distribute 4 to 2 and - x:

8-4x+15=3 (x+3)

2) Distribute 3 to x and 3:

8-4x+15=3x+9

3) Combine alike terms:

23-4x=3x+9

4) Add 4x to both sides:

23=7x+9

5) Subtract 9 from both sides:

7x=14

6) Divide both sides by 7:

x=2
