234-y=220

To solve the equation \( 234 - y = 220 \), we can isolate \( y \) by subtracting 234 from both sides:

\[ 234 - y = 220 \]

Subtract 234 from both sides:

\[ -y = 220 - 234 \]

Calculating the right side:

\[ -y = -14 \]

Now, multiply both sides by -1 to solve for \( y \):

\[ y = 14 \]

Thus, the solution is:

\[ y = 14 \]
