how fast you want it ?

anonymous · Answer

i mean "explanation" or how i would get the answer in three seconds?

naga447 · Answer

As fast as you can explain it to me lol

naga447 · Answer

I'd like to know what I'm doing

anonymous · Answer

$$y-2x=-1\
x+3y=4$$ rewrite so they line up 
$$-2x+y=-1\
x+3y=4$$

anonymous · Answer

now the x over the x and the y over the y 
multiply the second equation by 2 
$$-2x+y=-1\2x+6y=8$$

anonymous · Answer

add in a column so the x terms go bye bye leaving $$7y=7$$ which makes $y=1$

naga447 · Answer

Okay that helped a lot! having someone go though the steps! Thank you very much~

anonymous · Answer

yw
once you have $y=1$ i hope it is clear how to find $x$

naga447 · Answer

I I just do basically the same thing except I'd be solving for x

anonymous · Answer

no no you don't need all that

anonymous · Answer

since $$x+3y=4$$ and $y=1$ you have 
$$x+3=4$$ making $x=1$

naga447 · Answer

Oh lol that's much simpler than redoing all of that  thank you again!

anonymous · Answer

sure is !
