who will work? you or me?
its Solving Linear Systems Using Linear Combinations
idk how to work them out
willing to work?
willing to work?...i dont understand
You don't know how to do, but if I guide and YOU are willing to work, we can work together to get the answer. If you don't want to work on it, OOOOOOOOOOOOOK, both us go to bed. hahahaha....
well yea im willing to work on it
ok, what is the fist equation?
x − 3y = 4?
yup, multiply both sides by 2, what do you get?
idk its jus there
ooooooo ok so u distribute
yup, now what is the second equation?
2x + y = 7
ok, let them close to each other, and then subtract them, what do you have?|dw:1433204441490:dw|
idk how u would get it
You should be aware that I am ssssssssssso patient. I won't indulge you. You must work on it by yourself
-7y =1 okkkkkk
divide both sides by -7 , what do you get?
or positive 7
so when u divide 1 by a larger # it becomes a fraction?
now, replace y = -1/7 into the second equation, what do you get?
+1/7 both sides.
tbh im kinda confused on this step
your ORIGINAL second equation is 2x +y = 7 replace y = -1/7 in, you have 2x-1/7 =7. Why confuse?
ok i get tht part
now, you have 2x = 50/7 divide both sides by 2, you get x. combine with y =-1/7 above, you have the solution. done
ok i get it thx i appreciate it
