Answer:
3
Step-by-step 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!
