Answer
$\{(-\frac{3y+7}{2},y)\}$
Work Step by Step
1. Simplify the first equation (divide by 3) to get $2x+3y=-7$
2. Simplify the second equation (divide by 2) to get $2x+3y=-7$ which is the same as above.
3. Thus the system has infinitely many solutions.
4. Solve for $x$ from the first equation to get $x=-\frac{3y+7}{2}$
5. Thus the solution set is $\{(-\frac{3y+7}{2},y)\}$
