2 Points
Use the substitution method to solve the system of equations. Choose the
correct ordered pair.
2x+ 2y = 16
y=x
- 4
O A. (2,-2)
O B. (6, -2)
O C. (6,2)​

Respuesta :

Answer:

C

Step-by-step explanation:

THe equation given is

2x+2y=16

y=x-4

We put 2nd equation in first equation and first solve for x:

[tex]2x+2y=16\\2x+2(x-4)=16\\2x+2x-8=16\\4x=16+8\\4x=24\\x=\frac{24}{4}\\x=6[/tex]

Now, since we know y = x - 4, we substitute x = 6 and get y:

y = x - 4

y = 6 - 4

y =2

The correct ordered pair is (6,2), answer choice C
