To solve the equation \( 248 - (y + 128) = 24 \), we can follow these steps:
Distribute the negative sign inside the parentheses: \[ 248 - y - 128 = 24 \]
Combine like terms on the left side: \[ 120 - y = 24 \]
Isolate \( -y \) by subtracting 120 from both sides: \[ -y = 24 - 120 \] \[ -y = -96 \]
Multiply both sides by -1 to solve for \( y \): \[ y = 96 \]
So the solution is \( y = 96 \).
