Question

What is the solution for this equation X/2-7=9

Answer 1

$\frac{x}{2}-7=9\ \ \ \ | add\ 7\\\\ \frac{x}{2}=16\ \ \ | multiply\ by\ 2\\\\ x=32\\\\Solution\ is\ x=32.$

Answer 2

$\frac{x}{2}$-7 = 9 First you want to get the variable by itself on one side of the equastion, so you add 7 to both sides of the equal sign... $\frac{x}{2}$ -7 = 9
        + 7  + 7
      ------------------
$\frac{x}{2}$ = 16 Then since x is being divided by two, you multiply by two on both sides of the equals sign, to get x completely by itself

$\frac{x}{2}$ = 16
x 2                              x 2
------------------------------------------
x = 32 
Then to see if your answer is correct, you plugin 32 for x, and the statement will be correct. $\frac{32}{2}$ - 7 = 9
                                16 - 7 = 9 
                                 9 = 9  The statement is correct so your solution for x is correct as well.
