-9(8-9x)=4x+5

To solve the equation \(-9(8 - 9x) = 4x + 5\), follow these steps: 1. Distribute the \(-9\) on the left side: \[ -9 \cdot 8 + 9 \cdot 9x = -72 + 81x \] So the equation becomes: \[ -72 + 81x = 4x + 5 \] 2. Next, let's move all terms involving \(x\) to one side and constant terms to the other side. First, subtract \(4x\) from both sides: \[ -72 + 81x - 4x = 5 \] This simplifies to: \[ -72 + 77x = 5 \] 3. Now, add \(72\) to both sides: \[ 77x = 5 + 72 \] Which simplifies to: \[ 77x = 77 \] 4. Finally, divide both sides by \(77\): \[ x = \frac{77}{77} \] Therefore: \[ x = 1 \] The solution to the equation \(-9(8 - 9x) = 4x + 5\) is \(x = 1\).
