2x - y = 8 x + y = 1 These are your two equations. They will have two solutions since you have two variables. The solutions are x=3 and y=-2

Your question does not make sense.
It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
One
There is one solution for x and one solution for y. The solution is: x = -1 ; y = 2
There are a number of possible solutions which will have x=2 and y = 10 as solutions but many of them will also allow other solutions. One possibility, with a unique solution, is (x-2)2 + (y-10)2 = 0
Two solutions and they are:- x = 0 and y = 3
The solutions are: x = 4, y = 2 and x = -4, y = -2
