I'm assuming that the equation should be abs%28x%2B2%29=11


abs%28x%2B2%29=11 Start with the given equation


Break up the absolute value (remember, if you have abs%28x%29=a, then x=-a or x=a)


x%2B2=-11 or x%2B2=11 Set the expression x%2B2 equal to the original value 11 and it's opposite -11


Now lets focus on the first equation x%2B2=-11


x=-11-2Subtract 2 from both sides


x=-13 Combine like terms on the right side


Now lets focus on the second equation x%2B2=11


x=11-2Subtract 2 from both sides


x=9 Combine like terms on the right side


So the solutions are: x=-13 or x=9
