How many solutions are there to the equation below. 9x+27=9 (x+2) + 9

All Real Numbers Are Solutions

Explanation:

9x + 27 = 9 (x + 2) + 9

Simplify both sides of the equation.

9x + 27 = 9 (x + 2) + 9

9x + 27 = (9) (x) + (9) (2) + 9 (Distribute)

9x + 27 = 9x + 18 + 9

9x + 27 = (9x) + (18) (Combine Like Terms)

9x + 27 = 9x + 27

9x + 27 = 9x + 27

Subtract 9x from both sides.

9x + 27 - 9x = 9x + 27 - 9x

27 = 27

Subtract 27 from both sides.

27 - 27 = 27 - 27

0 = 0

Therefore, all real numbers are solutions.
