Question

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

Answer 1

Infinite solutions.

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.
