Question 199616
Let x=unknown number


What you want to solve is {{{abs(x)=7}}}



Break up the absolute value to get 


{{{x=-7}}} or {{{x=7}}} 



Note: if {{{abs(x)=a}}}, then {{{x=-a}}} or {{{x=a}}})



So the solutions are {{{x=-7}}} or {{{x=7}}} which means that the absolute value of -7 or 7 is 7.
