Use the elimination method to solve the system of equations choose the correct order pair.

6x + 4y=32
-6x + 4y =8

0,8
1,5
2,5
4,2

Respuesta :

Answer:

Its the third choice:

(2, 5).

Step-by-step explanation:

6x + 4y = 32

-6x + 4y = 8     Adding the 2 equations:

0 + 8y = 40

8y = 40

y = 5

Now substitute for y in the first equation:

6x  + 4(5) = 32

6x = 32 - 20 = 12

x = 2.

Add equation 1 and 2 to remove 6x. You will end up with
[tex]8y = 40[/tex]
By solving, y=5

Sub 5 into any equation
[tex]6x + 4(5) = 32[/tex]
By solving, x=2
The ordered pair is (2,5)
