Question

Determine the cost for one candle?

Answer 1

Explanation:

2c + h =16 <- 1

4c + 3h = 34 <-2

1 to 2

3[2c+h = 16]3

=6c +3h = 48 <-3

3 to 2

6c +3h = 48

- 4c + 3h = 34

-----------------------------

2c = 14

c= 7

substitue C=7 to equation 1

2(7) + h =16

14 + h = 16

h = 2

Therefore 7 and 2 is the answer
