Are you asked to solve the system of equations?

Yes

Okay, then take the second equation:
$$7x = 3(2y) + 3$$
And multiply the right-hand side out:
$$7x = 6y + 3$$
Divide both sides by 7:
$$x = \frac{6y + 3}{7}$$
Substitute this into the first equation:
$$2 \times \frac{6y + 3}{7} + 3y = 0$$
Multiply both sides by 7:
$$2 \times (6y + 3) + 21y = 0$$
Multiply out:
$$12y + 6 + 21y = 0$$
Combine like terms:
$$33y + 6 = 0$$
Rewrite this equation with just y = on one side to get your y-value, then substitute that back into the second equation to find the x-value.

You're welcome.  They usually turn out cleaner than that... >_<
