2x + 3y = k
2(2) + 3(0) = k
4 = k
k = 4
2.50$ is the better deal. If you times 0.70$ to 5 it is 3.5$ which is more expensive
Answer:

Step-by-step explanation:
According to the question, the equation will be:
⇒
...(equation 1)
or,
⇒ 
...(equation 2)
Now,
By multiplying (equation 1) by 55 and (equation 2) by 1, we get
⇒
...(equation 3)
⇒
...(equation 4)
From equation 3 and 4, we get
⇒ 


By putting the values of "y" in equation 1, we get
⇒ 

Thus the value of x be "24 pounds".
