Step-by-step explanation:
Errrr....this is kind of big brain for me. also i'm new here. hope somebody else can answer you.
{ x + 2y = 4 * ( 3 )
-3 x + 2y = -4
3 x + 6 y = 12
-3 x + 2 y = -4
---------------------
8 y = 8
y = 8 / 8
y = 1
For x :
x + 2 y = 4
x + 2*(1 ) = 4
x + 2 = 4
x = 4 - 2
x = 2
Answer C ( 2 , 1 )
hope this helps!
