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:

We expand to obtain;

This implies that:

Therefore the system has infinitely many solutions.
Answer:
1 bowl = 1/3 cups
