Question

Is either x = 9 or x = 15 a solution to x-3 = 12?

Answer 1

Its 15 (x=15)

Explanation:

I mean 15-3 is 12

Answer 2

x = 15 is your solution.

Explanation:

To find out what your answer is, plug in the given solutions for the variable, x, in the given equation:

When x = 9:

x - 3 = 12

(9) - 3 = 12

6 ≠ 12

When x = 15:

x - 3 = 12

(15) - 3 = 12

12 = 12
