Solve the System : 1/x - 3/y = -3 2/x - 1/y = 4
So isolate x for 1/x-3/y = -3 and you'll get x=-y/(3y-3) Next, substitute x=-y/(3y-3) into your equation to get your "y" value. So you'll get y=1/2 Finally, plug in y=1/2 into your original equation to your "x" and you'll get x=1/3 and y=1/2 as your final answer If you found this helpful, I encourage to subscribe to our youtube channel https://www.youtube.com/channel/UCYiI7SmkU4_vhdSzKBWsifg to stay current with all of our new videos.

i will as soon as i am done studying i have a question about the second part of your answer i do not understand what i have to do
So this basic method is called substitution. Here's how it works: you pretty much find a variable and you take it all by itself. For example if you have x+2=4y... you'll take "x" all by itself so x=4y-2 .... then when you separated one variable from the entire equation you'll plug it back to the formula to find your other variable.
wow that is really confusing thank you for your help though
You still need help on this?
yes please
ok.
