Question is in picture PLEASE HELP

Step-by-step explanation:

Hello,

For the step 1:

We multiply the first equation by 3 and the second equation by 2, so we are using the Multiplication Property of Equality.

For the step 2:

To eliminate the x we subtract the first equation to the second one, so we are using the Subtraction Property of Equality.

For the step 3:

We divide by -16 both parts of the equation, so we are using the Division Property of Equality.

For the step 4:

We replace y in the initial first equation, we we are using the Substitution Property of Equality.

For the step 5:

We just Simplify.

For the step 6:

We add 4 to both parts of the equation, so we are using the Addition Property of Equality.

For the step 7:

We divide by 2, so we are using the Division Property of Equality.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
