Question 334117
You can't solve it because there are 2 unknowns.
If there were 1 unknown, you could solve it. You
can get either {{{x}}} or {{{y}}} alone on one side,
however. I'll find {{{y}}} in terms of {{{x}}}
{{{2y + 6 > -2x}}}
Subtract {{{6}}} from both sides
{{{2y > -2x - 6}}}
{{{y > -x - 3}}}
To simplify, divide both sides by {{{-1}}}, and 
change the > sign to a < sign.
{{{y < x + 3}}}
