A system of equations has 1 solution. If 4x-y=5 is one of the equations which could be other equation?

Step-by-step explanation:

Try this: Starting with 4x-y=5, change either the coefficient 4 or the coefficient 1 to another value (for example, 3x - y = 5). Then check to see whether the original and this new line intersect; you will find that they do.

Changing one of the coefficients changes the slope.
