Answer
$x=6$
Work Step by Step
$6-(-5)=x+5\rightarrow$ simplify
$11=x+5\rightarrow$ subtract 5 from both sides
$11-5=x+5-5\rightarrow$ simplify
$6=x$
Check the solution by plugging in the value for y and determine whether the resulting equation is true.
$6-(-5)=6+5\rightarrow$ simplify
$11=11$
This is true so the solution is correct.
