Solve for x and y in congruent triangles ΔBOY and ΔGRL to find missing side lengths and angles.
Two congruent triangles, ΔBOY and ΔGRL, with labeled sides and angles; ΔBOY has angle B = 93°, side BO = 2x + 3, side OY = 15, and ΔGRL has side GR = 12, side RL = 11, angle L = 48°, and side GL = 3y - 6. Solve for x and y to find missing parts.
