Answer:

3

Explanation:

4x + 2y = 12

x − y = 3

Make it able to cancel the variable y.

x*2 − y*2 = 3*2

2x − 2y = 6

Add the equations together now that y can be canceled out. Add each like term of the separate equations together.

4x + 2y = 12

+ 2x − 2y = 6

6x + 0 = 18

6x = 18

6 6

x = 3

I hope this helps!
