Answer:

x = 9

Explanation:

The easiest way you can do this is to set both expressions equal to each other and solve for x.

2x + 3 = 3x - 6 (subtract 2x from both sides to get x on one side)

3 = x - 6 (add 6 to both sides to get x by itself)

9 = x aka x = 9

You can double-check your answer by plugging in 9 for x in both expressions.

2(9) + 3 = 21

3(9) - 6 = 21
