Solve the system of Linear Equations USING substitution method
x = y +4
2x + 2y = 16

x = 8

y = 4

Step-by-step explanation:

x = y + 4

2x + 2y = 16

Substitution Method

We know that we need to use the substitution method, since we see that the first equation has x alone, we can substitute it with the x's in the second equation.

x = y + 4

2x + 2y = 16

2(y + 4) + 2y = 16

Distribute :

2y + 8 + 2y = 16

Add like terms :

4y + 8 = 16

Subtract 8 from both sides :

4y = 8

Divide 4 from both sides :

y = 4

Now that y is 4, substitute it into the first equation to get x :

x = (4) + 4

4 + 4

8

x = 8

all you   do is count how many times you move

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
