Answer:

Ordered pair (x,y) is (6,2)

Step-by-step explanation:

Use the substitution method to solve the system of equations.

2x + 2y = 16    -----> first equation

y=x-4 -------> second equation

Divide the first equation by 2

2x + 2y = 16    -----> first equation

x+y=8    

Now solve for y, subtract x from both sides

y=-x+4    

Now plug in -x+8 for y in second equation

y=x-4 -------> second equation

-x+8=x-4  

Subtract x from both sides

-2x+8=-4  

Subtract 8 on both sides

-2x=-12  

Divide both sides by -2

x=6

now we plug in 6 for x in second equation

y=x-4 -------> second equation

y=6-4

y=2

Ordered pair (x,y) is (6,2)
