X= -8y + 8
x= -2y + 2
How do I solve this system of equations

According the the Property of Equality (POE), if a=b and b=c, then a=c.

If -8y + 8 = x and x = -2y + 2, substitute so that it becomes -8y + 8 = -2y + 2.

Solve from there:

Move the y variables to their own side.

-8y + 2y = 2-8

-6y = -6

y = -6

Then plug the y into either equation to find x.

x = -2y + 2

x = -2(-6) + 2

x = 12 + 2

x = 14

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
