only one.
look at the problem.
x = 8
x has to equal 8.
hope i helped! :)

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
X = 8That equation has exactly one solution.The solution is:x = 8
one
If: x-3 = 8 then x = 11 which has only one solution

Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
Only one: (3,-2)
Infinitely many: they are the same line!

Only 1.
It has two solutions and they are: x = 3.230396696 and x = -2.063730029
A solution to an linear equation cx + d = f is in the form x = a for some a, we call a the solution (a might not be unique). Rewrite your sentence: x = 8, 8 is unique. So how many solution does it have?
