Can I solve and get the coordinates by elimination process?
that's right, use elimination
Ok thank you
How would that work with x and 9y's being in the same spots? Which one would I eliminate?
f(x) = −2x + 8, find x if f(x) = 22 -2x+8 = 22 -2x = 22-8 -2x = 14 x = -7
that's for ur other question
x+9y=6 x-9y=5 x=1?
the equation should be: x+9y=6 x-9y = -5
Oh ok so the answer would be x=1? right?
hmm, how did u get it? show me
I did x+9y=6 and then added x-9y=-5 and canceled out the 9y-9y, and then 6-5 is one leaving me with x=1.
Does that make sense?
ok, bad at math, we can do another way, which is subtitution. we have: x+9y=6 x=9y-5 then just plug x=9y-5 into x+9y=6
I'm sorry I just became very confused
I did x+9y=6 and then added x-9y=-5 and canceled out the 9y-9y, and then 6-5 = 1, till this u are right, but u forget to do x+x = 2x 2x=1 x =1/2
So then to find y I replace x with 1/2? right
ok so I do that for both equations too right?
no need, do it just to 1 equation
ok what do I do with the y in the equation I do? Sorry I am stupid at this
x = 1/2, plug into x+9y=6
ok so that would be 1/2+9y=6
ok than would I subtract/add 9y to both sides?
9y = 6 - 1/2, got it?
I think, so to find y I would make the equation like this 2*1/2-9y=6 1-9y=6 -9y=5 y=-.6?
is that even close to right?
2*1/2-9y=6 ---> it's mean 2x-9y = 6 --->but our equation is x+9y=6 my answer : 1/2 +9y=6 9y = 11/2 y = 11/18 (x,y) = (1/2 , 11/18) to check ur question is correct or no, plug the order pair into initial equation: x+9y=6 1/2 + 9(11/18) = 1/2 + 11/2 = 12/2 = 6
ok, thank you so much for help
