The given equation is
[tex]u+2=9u+2=9[/tex]That means
[tex]u+2=9,9u+2=9[/tex]We will solve both equations to find u
[tex]\begin{gathered} u+2=9 \\ u+2-2=9-2 \\ u=7 \end{gathered}[/tex]For the 2nd equation
[tex]\begin{gathered} 9u+2=9 \\ 9u+2-2=9-2 \\ 9u=7 \\ \frac{9u}{9}=\frac{7}{9} \\ u=\frac{7}{9} \end{gathered}[/tex]Since the values of u so not equal, then
The equation has no solution
Then No value for u
