how do you think you'll go about this? can you try substituting one variable in terms of the other?
i wanted to try substituting but i didnt think it would work because the answers here are like this (x,y) and (x,y). Its asking for two sets of answers
i know how to get the first set but then how would i start to get the second?
Think about it like this: when you use substitution for two-variable linear equations, you solve for only one variable. Then you substitute the value you found BACK into the equation to find the value of the other variable.
(0,-3),(3,0) (0,3),(-3,0) (0,3),(3,0) (0,-3),(-3,0) these are the answers. see what i mean?
I think its (0,3),(-3,0)
You're given the answers. Why not try to substitute these into the equations and see which ones are correct? ;P
Does (-3, 0) satisfy x + y = 3? See what I'm talking about?
I see what you are saying. I was so clueless. Thanks!
I think the only answer is (0,3), (-3,0)
yea. its the only one that works
Again, I ask: does (-3, 0) satisfy x + y = 3?
because -3+0 doesnt equal 3
OHH. ITS (0,3), (3,0)
i've been up for 34 hours taking finals. sorry
I neede to get this done before i took my math final
