Question
2x-y=3
3x+3y=5
solve the system is it no solution, infinite solution or unique solution

Using the 1st equation, it is seen that y = 2x - 3.
Putting that in the 2nd equation gives 3x + 3(2x-3) = 5.
That is, 3x + 6x - 9 = 5, so 9x = 14.
That says x = 14/9.

Using 2x - y = 3, that is 28/9 - y = 27/9, so y = 1/9.

Checking this by using the 2nd equation gives 3x + 3x = 42/9 + 3/9 = 45/9 = 5,
and that is correct.
