One way to solve this problem, is to use the method of linear combinations:
4x - y = 3 ---> multiply by -2 ---> -8x + 2y = -6
6x - 2y = 5 ---> 6x - 2y = 5
Add down the columns: -2x = -1
Divide by -2: x = -1/-2 ---> x = 1/2
Replace this value into the first equation: 4x - y = 3 ---> 4(1/2) - y = 3
---> 2 - y = 3 ---> -y = 1 ---> y = -1
