To solve for x, we need to isolate x on one side of the equation.
First, we can multiply both sides of the equation by 9 to get rid of the denominator:
9 * (12 - x)/9 = 11 * 9
12 - x = 99
Next, we can subtract 12 from both sides of the equation to isolate x:
12 - x - 12 = 99 - 12
-x = 87
Finally, to solve for x, we need to multiply both sides of the equation by -1:
(-1)(-x) = (-1)(87)
x = -87
Therefore, the solution to the equation is x = -87.
Solve for x. 12−x/9=11
