Ok. so lets call the cost of each soda x. now, 3 packs of soda is 10 less than five packs of soda. so the price of 3 packs of soda is 3x, the price of five packs is 5x. now, it says that 3 packs is 10 less than five packs. that means that 3x=5x-10.
now, to find the price of a pack of soda, we have to isolate x.
add 10 to both sides to get 3x+10=5x. now, we subtact 3x on both sides to get 10=2x. divide by 2 on both sides, x=5. a pack of soda is 5 dollars

Answer:

The answer to your question is the big dog weighs 120 pounds

Step-by-step explanation:

Data

big dog = b

medium dog = m

small dog = s

Equations

b = 5s

m = 12 + s

s = 2/3 m

Process

1.- Substitute m in the last equation

s = 2/3(12 + s)

s = 24/3 + 2/3s

s - 2/3s = 8

1/3 s = 8

s = 8(3)

s = 24 pounds

2.- Substitute s in the first equation

b = 5(24)

b = 120 pounds
