Answer:
x = 9/4 or 2.25
Step-by-step explanation:
First you will combine like terms. Combine 2x + 3x - x which gives you 4x. Then combine 9 - 2 and you get 7. Now the equation is 4x + 7 = 16. Subtract 7 from both sides to get x by itself. Now you have 4x = 9. To find what x equals, divide by 4 on each side. x = 9/4 or 2.25
