Given:
The equation for u is 11u - 3 = 8.
Explanation:
Simplify the equation to obatin the value of u.
[tex]\begin{gathered} 11u-3=8 \\ 11u=8+3 \\ u=\frac{11}{11} \\ =1 \end{gathered}[/tex]
So value of u is 1.
Substitute 1 for u in the expression 3u - 10 to obtain the value.
[tex]\begin{gathered} 3u-10=3\cdot1-10 \\ =3-10 \\ =-7 \end{gathered}[/tex]
So avlue of expression is -7.
Answer: -7
