Check my work. I think that this system of equation has infinite numbers of solution. System: 2y + 6 = 4x and - 3 = y - 2x. So I solved the first equation for y. So first I subtracted 6 from both sides and got 2y = 4x - 6, then I dived both sides by 2 and got y = 2x - 3. For the second equation I solved for y by subtracting y from both sides and got y + 3 = - 2x, then I subtract 3 from both sides and got y = 2x - 3. Is this correct?
