Question 939217: Apples are 92 cents a pound, and pears are $1.22 a pound. If I spend $4 and the weight of the apples I buy is twice the weight of the pears, how many pounds of pears do I buy?
Round your answer to three decimal places. Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = pounds of apples
y = pounds of pears
---
x = 2y
0.92x + 1.22y = 4
---
put the system of linear equations into standard form
---
x - 2y = 0
0.92x + 1.22y = 4
---
copy and paste the above standard form linear equations in to this solver:
