How many solutions (s) does the system of equations have? -5x+y=-18 and 10x-2y=36

The system of equations can be written as:

-5x + y = -18
10x - 2y = 36

We can rewrite the first equation as:

y = 5x - 18

Substitute this expression for y into the second equation:

10x - 2(5x - 18) = 36
10x - 10x + 36 = 36
36 = 36

Since the equation is always true, it means that the system of equations has infinitely many solutions.
