Answer:

2x - y = 8 \\  \: 2x = 8 + y \\ x =  \frac{8 + y}{2} ..............(i) \\  \\ 6x + y = 16 \\ 6 \times  \frac{8 + y}{2}  + y =  16 \:  \:  \:  \: (from \: eq(i)) \\ 24 + 3y + y = 16 \\ 24 + 4y = 16 \\ 4y =  - 8 \\ y =  - 2............(ii) \\  \\ 6x + y = 16 \\ 6x  - 2 = 16 \\ 6x = 18 \\ x = 3

The value of x is 3 and y is -2
