Answer:
He needs 3.75 lbs of sugar and 1.25 lbs of water.

So, he needs 3.75 lbs of sugar and 5 - 3.75 = 1.25 lbs of water.
Answer:
x = 5/2
y = -1/2
Step-by-step explanation:
if both equations start with 'y=' then set the expressions equal to each other
3/5x - 1 = x - 3
add 1 to each side to get:
3/5x = x - 1
subtract 5/5x from each side:
3/5x - 5/5x = -1
-2/5x = -1
multiply each side by -5/2:
x = 5/2
y = 2 1/2 - 3
y = -1/2
