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
Infinitely many: they are the same line!

It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
Two solutions and they are:- x = 0 and y = 3

The solutions are: x = 4, y = 2 and x = -4, y = -2
[x + y = 6] has an infinite number of solutions.
It works out that the solutions are: x = 3 and 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
