Solve the system of linear equations.
15x - 5y = -20
-3x + y = 4

Infinite solutions.

Step-by-step explanation:

Use the elimination method:

15x - 5y = -20

-3x + y = 4              Multiply this equation by 5:

-15x + 5y = 20         Now add this to the first equation:

0 = 0

So the 2 equations are the same and there are infinite solutions.
