Answer:
(x, y) = (-2, -1) or (2, 1)
Step-by-step explanation:
Substitute for x in the first equation:
(2y)^2 +3(2y)y = 10
10y^2 = 10
y^2 = 1
y = ±1
x = 2y = ±2
Solutions are (x, y) = (-2, -1) or (2, 1).

x=5
AB=x, AB =5
BC=3x BC= 15
Answer: There will be 5 packages of small juice bottles and 3 packages of yogurt.
Step-by-step explanation:
Number of packages of small juice bottles=6
Number of packages of yogurt = 10
