To rewrite the equation in terms of \( t \), we can use the given equations \( 3t + 2g = 51 \) and \( t + g = 21 \).
From the second equation, we can solve for \( t \):
\[ t + g = 21 \]
Subtract \( g \) from both sides:
\[ t = 21 - g \]
Now we have \( t \) expressed in terms of \( g \). If you substitute \( t = 21 - g \) back into the first equation, you can solve for \( g \) if needed.
