Question

Use the elimination method to solve the system of equations. 6x+4y=32 -6x+4y=8

Answer 1

(2,5)

Explanation:

6x+4y=32

-6x+4y=8

We will add the two equations together to eliminate x

6x+4y=32

-6x+4y=8

----------------------

8y = 40

Divide each side by 8

8y/8 = 40/8

y = 5

Multiply the first equation by -1

-6x-4y = -32

-6x+4y=8

------------------

-12x = -24

Divide by -12

-12x/-12 = -24/-12

x = 2
