Solve for x: x - 9 = 15

A. 6

B. 24

C. - 24

D. - 6

The answer is B. 24.

A isn't going to work, since 6 is less than 9. It'd give you a negative number.

D won't work, either, it'd give you - 15. Again, you'd get a negative number.

C won't work for the same reasons as last time, it'd give you a negative number.

B gives you the exact number we're looking for, and it's a positive number.

X = 24

Step-by-step explanation:

Add 9 To Both Sides

X - 9 + 9 = 15 + 9

Simplify

X = 24

Best Of Luck,
