ANSWER
x = 50
EXPLANATION
In this equation, to find the value of x, first, we have to subtract 1 from both sides,
[tex]\begin{gathered} x\div5+1-1=11-1 \\ \\ x\div5=10 \end{gathered}[/tex]And then, multiply both sides by 5,
[tex]\begin{gathered} x\div5\times5=10\times5 \\ \\ x=50 \end{gathered}[/tex]Hence, the value of x is 50.
