Final answer:
Solving the equation 12 - x/9 = 11 involves isolating the term with x, resulting in x/9 = 1, and then multiplying by 9 to find that x = 9.
Step-by-step explanation:
To solve for x in the equation 12 - x/9 = 11, follow these steps:
- Add x/9 to both sides of the equation to isolate the term with x on one side:
12 = 11 + x/9 - Subtract 11 from both sides to get the expression with x by itself:
x/9 = 12 - 11
x/9 = 1 - Multiply both sides by 9 to solve for x:
x = 1 * 9
x = 9
The solution to the equation is x = 9.
