63-(25+z)=26

To solve the equation \( 63 - (25 + z) = 26 \), first, let's simplify the left side:

1. Distribute the negative sign: \[ 63 - 25 - z = 26 \]

2. Combine like terms: \[ 38 - z = 26 \]

3. Now, isolate \( z \): \[ -z = 26 - 38 \] \[ -z = -12 \] \[ z = 12 \]

Therefore, the solution is \( z = 12 \).
