Question

What is the value of the x variable in the solution to the following system of equations?

4x + 2y = 6
x – y = 3

−1

5

−2

2

Answer 1

The answer should be 2. I used elimination

Answer 2

2

Answer 3

I multiplied the second equation by 4 which gave me:4x-4y=12
Then I subtracted to eliminate the x
4x-4x=0x 2y-(-4y)=6y 6-12=-6
6y=-6
y=-1
Now you must plug in the y value into one of the equations and solve for x:
x-(-1)=3
x=2
