The system of equations x - y = 8 and x + y = 4 has to be solved for x and y.

Add the two equations, x - y + x + y = 8 + 4

=> 2x = 12

=> x = 6

x - y =...

The system of equations x - y = 8 and x + y = 4 has to be solved for x and y.

Add the two equations, x - y + x + y = 8 + 4

=> 2x = 12

=> x = 6

x - y = 6 - y = 8

=> y = -2

**The solution of the given system of equations is x = 6 and y = -2**
