solve for x

12-x/9=11

1 answer

To solve for x, first we need to isolate the variable x by getting rid of the fraction.

12 - x/9 = 11

To get rid of the fraction, we can multiply both sides by 9:

9(12 - x/9) = 9(11)
108 - x = 99

Now, solve for x by isolating it on one side:

-x = 99 - 108
-x = -9

Multiply by -1 to solve for x:

x = 9

Therefore, the solution to the equation is x = 9.
