Question

I WILL MEDAL AND FAN
What is the solution for the following system?
3x+3y=10
-9x-9y=-30

Answer 1

hi

Answer 2

I have Nooo idea how to answer that question

Answer 3

me ehthier

Answer 4

either

Answer 5

Hmmm... normally I would suggest using the elimination method to solve it... but that doesn't come out to anything.

Answer 6

yeah its not even a multiple choice i have to do steps for it but its super confusing to me.

Answer 7

The only thing I can think of out of the box is that x and y equal 1.67(1 2/3) which gives you half of the sum amount, other than that there is nothing specific to work with since you know neither x or y... what a confusing question...
I hope that helps in someway and perhaps is the answer. Have a great day!

Answer 8

if you multiply the first equation by -3 you will see that it comes out as exactly the same equation as the second.

Therefore these are not 2 independent equations and do not have a unique solution

Answer 9

Normally if you graph the 2 equations there will be one point of intersection

BUT in this case the 2 lines co-incide at all points - so there is no unique solution

Answer 10

I already got it but thank you.

Answer 11

and what did oyu 'get'?
