Given:

The equation for u is 11u - 3 = 8.

Step-by-step explanation:

Simplify the equation to obatin the value of u.


\begin{gathered} 11u-3=8 \\ 11u=8+3 \\ u=(11)/(11) \\ =1 \end{gathered}

So value of u is 1.

Substitute 1 for u in the expression 3u - 10 to obtain the value.


\begin{gathered} 3u-10=3\cdot1-10 \\ =3-10 \\ =-7 \end{gathered}

So avlue of expression is -7.
