Answer

$x=0$

Work Step by Step

Using the properties of equality, the solution to the given equation, $ 11=11(x+1) $, is \begin{array}{l} 11=11x+11 \\\\ 11-11=11x \\\\ 0=11x \\\\ x=\dfrac{0}{11} \\\\ x=0 .\end{array} CHECKING: \begin{array}{l} 11=11(0+1) \\\\ 11=11(1) \\\\ 11=11 \text{ (TRUE)} .\end{array} Hence, the solution is $ x=0 $.
