These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
Only one: (3,-2)
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
Just one.
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

It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
Only one: (3,-2)
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.
How many solutions are there to the following system of equations?2x - y = 2-x + 5y = 3if this is your question,there is ONLY 1 way to solve it.
Just one.
Through a process of elimination and substitution the solutions are s = 8 and x = 5
Each of the two equations has an infinite number. Simultaneously, they have only one.
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
We believe that those equations have no real solutions, and that their graphs therefore have no points of intersection.
There are two solutions and they are: x = -1 and y = 3
