To combine like terms in the expression \(50uvw + 44uvw + 48 - 11uvw\), we first identify the like terms, which are those that contain the variable \(uvw\).
Let's combine the coefficients of \(uvw\):
- \(50uvw + 44uvw - 11uvw\)
Calculating this:
\[ 50 + 44 - 11 = 83 \]
So, the combined term for \(uvw\) is \(83uvw\).
Now we can rewrite the expression, including the constant term \(48\):
\[ 83uvw + 48 \]
Thus, the simplified expression is:
\[ \boxed{83uvw + 48} \]
