Question

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

Answer 1

4x + 2y = 6
x – y = 3

Answer 2

−1

5

−2

2

Answer 3

Solve by using elimination.

Answer 4

4x + 2y = 6
x – y = 3 double the second one get
\[4x+2y=6\]
\[2x-2y=6\]

Answer 5

and them up in a column, get
\[6x=12\] and so \(x=2\)

Answer 6

I thought you add the two equations together?
