but can you tel me why ?

anonymous · Answer

You could actually solve for either of the variables in either of the equations. Any of these answers are correct. Does the question give any more info?

anonymous · Answer

@JBrightman3 There actually is a logical reason. Look more closely.

anonymous · Answer

@jhonyy9 i think its C bcuz it seems like the easiest way to solve it

@Calcmathlete I still don't see it. :/

jhonyy9 · Answer

good luck

anonymous · Answer

Look.
2x + 8y = 12
2x = -8y + 12
x = -4y + 6
See how the numbers go in evenly?

anonymous · Answer

I see, it is easier because there were no fractions involved. Thanks Calcmathlete. :)
