Hey MonkeyForLife,
Question:
Two small pitchers and one large pitcher can hold 8 cups of water. One large pitcher minus one small pitcher constitutes 2 cups of water. How many cups of water can each pitcher hold?
We Know:
All 3 picthers hold 8 cups together.
Solution:
8 - 2 = 6
6 - 4 = 2
2 - 2 = 0
Answer:
Small pitchers hold 2 cups.
Large pitchers hold 4 cups.
4 + 2 + 2 = 8
Answer: Larger pitcher holds 4 Cups of water, and the Smaller pitchers hold 2 Cups of water. ======> Answer: X = 4, Y = 2
Step-by-step explanation:
Solve the Equation:
x + 2y = 8
x - y = 2
Solve:
x + 2y = 8; x - y = 2
Solve:
x + 2y = 8 for x
x + 2y + -2y = 8 + -2y
Add -2y both sides:
x = -2y + 8
Substitute:
-2y + 8 for x in x - y = 2
x - y = 2
-2y + 8 - y = 2
-3y + 8 = 2
Simplify both sides:
-3y + 8 + -8 = 2 + -8
Add: -8 both sides
-3y = -6
-3y/ -3 = -6/-3
Divide both sides by -3:
y = 2
Step 2: Substitute:
2 for y in x = -2y + 8
x = 2y + 8
x = (-2 )(2) + 8
x = 4
Simplify both sides of equation:
Therefore, your answer for the larger pitcher holds, x = 4 cups of water, while the smaller pitchers hold, y = 2 cups of water.
Hope that helps!!!!! : )
