-4y=-20x+40 y+10=5x

Mathematics

Answer:

infinitely many solutions

Step-by-step explanation:

We want to find solution to the system:

-4y=-20x+40

y+10=5x

We make y the subject in the second equation to get;

y=5x-10

We substitute y=5x-10 into the top equation to get:

- 4(5x - 10) =  - 20x + 40

We expand to obtain;

- 20x  + 40=  - 20x + 40

This implies that:

40 = 40

Therefore the system has infinitely many solutions.
