In terms of y alone, just one solution. In the context of the Cartesian plane (or spaces in higher dimensions) an infinite number.
It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
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
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
Only one: (3,-2)
Infinitely many: they are the same line!
There is one solution for x and one solution for y. The solution is: x = -1 ; y = 2
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.
1
The solutions are: x = 4, y = 2 and x = -4, y = -2
There are infinitely many solutions, for example, x=-7 and y=5, because -7+5=-2
