Question 914555
Isolate the absolute value; in this case, simply multiplying left and right sides of equation by {{{1/3}}}.


Examine two cases separately.  Solve for {{{2x+5>=0}}}, and solve for {{{2x+5<0}}}.  Think logically about each of these cases about the signs of each step and decision.




Just to help with understanding,
Draw a number line and check how this works:
If {{{x>=0}}}, then {{{abs(x)=x}}}.
If {{{x<0}}}, then {{{abs(x)=-x}}}.
Also, if {{{x>=0}}}, then {{{abs(-x)=x}}}.
