Step-by-step explanation:
let x = the number of pounds of cheaper coffee.
Since the merchant is mixing this with more expensive coffee, then
x + 60 = the number of pounds of medium priced mixed coffee.
The equation is gotten from this
+ =
(x)($40) + (60)($90) = (x + 60)($70) or
40x + 5400 = 70(x + 60)
Solve that equation and get x = 40
Answer: 40 pounds of $40 coffee.

Answer:
x = -3 or x = -5/3
Step-by-step explanation:
Solve for x over the real numbers:
(x + 3) (3 x + 5) = 0
Split into two equations:
x + 3 = 0 or 3 x + 5 = 0
Subtract 3 from both sides:
x = -3 or 3 x + 5 = 0
Subtract 5 from both sides:
x = -3 or 3 x = -5
Divide both sides by 3:
Answer: x = -3 or x = -5/3
