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

x = 15 is your solution.

Step-by-step 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

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
