= x
Change y back into terms of x with x = (x) , then
(x) =

Answer:
the blue whale weighs 143.5 more tons than an African elephant
Step-by-step explanation:
an adult blue whale is 300,000 pounds, an adult African elephant is 13,000 pounds
300,000 pounds = 150 tons
13,000 pounds = 6.5 tons
150-6.5= 143.5 tons
Distribute -4 in this way:
-4(2x) - 4(-1) > 5 - 3x, to get
- 8x + 4 > 5 - 3x
