Solve for x. Type a numerical answer in the space provided. Do not use spaces in your answer. For example, if the answer is x = 15, type 15.

15x + 6 = 10x + 21

x=3

subtract 6 from both sides, then subtract 10x from both sides. You then have 5x=15; divide 5 from both sides and you get 3. Therefore, x is 3.

First, you subtract 10x from both sides, then subtract 6 from both sides. You are left with 5x = 15. Then, you divide both sides by 5 to get 1x = 3, so x = 3.
