Question

What is the solution to X+9 = 24? A. x = 33B. x= 15C. x= 18D. x= 9​

Answer 1

Answer:

B. x=15

Step-by-step explanation:

To find the solution to the equation, we must get x by itself on one side of the equation.

$x+9=24$

9 is being added to x. The inverse of addition is subtraction. Subtract 9 from both sides of the equation.

$x+9-9=24-9$

$x=24-9$

$x=15$

Let's check our solution. Plug 15 in for x.

$x+9=24 (x=15)$

$15+9=24$

$24=24$

This checks out, so we know our solution is correct. The answer is B. x=15

Answer 2

Answer:

X+9=24

Or,x=24-9
