How do you solve y equals x-3 and 2x equals y equals 3?

Answer 1

The second "equation" is, in fact, two equations, and the three equations are inconsistent.

The "second" equation gives :

2x = 3 so that x = 3/2 and also y = 3

But substituting these values in the first equation implies that 3 = (3/2) - 3

or 3 = 3/2 or 2 = 1 which is a contradiction.
