Solve for x . 12− x over 9 = 11 (1 point) x=

1 answer

To solve the equation \(\frac{12 - x}{9} = 11\), follow these steps:

  1. Multiply both sides by 9 to eliminate the fraction: \[ 12 - x = 11 \times 9 \]

  2. Calculate \(11 \times 9\): \[ 11 \times 9 = 99 \] This gives us: \[ 12 - x = 99 \]

  3. Now, isolate \(x\) by subtracting 12 from both sides: \[ -x = 99 - 12 \]

  4. Calculate \(99 - 12\): \[ 99 - 12 = 87 \] Therefore: \[ -x = 87 \]

  5. Finally, multiply both sides by -1 to solve for \(x\): \[ x = -87 \]

So, the solution is: \[ \boxed{-87} \]
