16-7(5-х)=9

To solve the equation \( 16 - 7(5 - x) = 9 \), follow these steps:

1. Distribute the \(-7\) through the parentheses: \[ 16 - 35 + 7x = 9 \]

2. Combine like terms: \[ -19 + 7x = 9 \]

3. Add 19 to both sides of the equation: \[ 7x = 28 \]

4. Divide by 7 to solve for \(x\): \[ x = 4 \]

Thus, the solution is \( x = 4 \).
