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.
