Question 1076123
Either both parts inside the absolute values are non-negative or both are negative or one of them is nonnegative while the other is negative.


x and x+1 non-negative:
{{{x=x+1}}}
This does not work!



x and x+1 opposite signs:
{{{x=-x-1}}}
{{{2x=-1}}}
{{{x=-1/2}}}



or


{{{-x=x+1}}}
{{{-2x=1}}}
{{{x=-1/2}}}


{{{highlight(x=-1/2)}}}
