Answer:

x - y = 5

x + y = 23

x = 14, y = 9

Step-by-step explanation:

Make x subject:

x = 5 + y

Substitute c by (5 + y) :

2y = 18

y = 9

x = 5 + 9

x = 14

If the equation below represents the total cost of 3 boxes of cereal and 2 loaves of bread is $15," then x represents
Liula [17]

Answer:

C. The cost of a box of cereal

Step-by-step explanation:

In the question, we are given the number of 3 boxes of cereal, 2 loaves of bread, and that the total cost is $15. We can see these numbers in the equation, and putting it into context, we see that the 15 is on the right side of the equation, which indicates cash. Therefore, the 3 and 2 are accounted for, but their prices are unknown. X is a placeholder for the unidentified cost of a box of cereal, and we know that it's the boxes of cereal and not the loaves of bread because there are 3 and not 2.
