Question

What is the solution to the following system of equations? 4x + 2y = 12 x − y = 3 (3, 0) (0, 3) (0, −3) (2, 3)

Answer 1

the answer is (3,0)

Explanation:

I took the test

Answer 2

Answer: First Option

(3, 0)

Explanation:

We have the following system of equations:

`4x + 2y = 12`

`x - y = 3`

To find the solution of the system of linear equations multiply the second equation by -4 and add it to the first equation

`4x + 2y = 12`

`-4x +4y = -12`

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

`0+6y=0`

`y=0`

Now substitute the value of y in the first or second equation:

`x - 0 = 3`

`x = 3`

The solution is: (3, 0)
