Question

Joe is mixing nuts and raisins to sell at a school fair. He buys nuts in 4-pound bags and raisins in 1-pound bags. x = number of bags of nuts he buys. y = number of bags of raisins he buys.

The following equations are true:

3x = y

4x + y = 70

Find the pairs of values for x and y that statisfy both equations simultaneously .
​

Answer 1

Answer:

10 ; 30

Step-by-step explanation:

we know from 1st equation that 3x = y

put value of y in 2nd equation

4x + y = 70

4x + 3x = 70

7x= 70

x= 10

so y = 3x = 30

y=30
