Answer:
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
