1. ## Simultaneous equation

Hi,
The answer to the simultaneous equation in the attachment is got by making x = (3y + 1) / 2;
however, shouldn't the equation work out by making Y = (2x - 1) / 3?
Thanks and I'd appreciate your help.

It depends on which variable you want to eliminate, in this case they have chosen to eliminate x.
