Question

anonymous · Answer

Whats the question and i will tell you if i do or not.

anonymous · Answer

alright

anonymous · Answer

solve the equation:

anonymous · Answer

4x^2+9y^2=36
x^2-4y^2=16

anonymous · Answer

do u know to solve it so u could help me please

anonymous · Answer

Yeah i know how to do it. I will post the steps

anonymous · Answer

alright thank you

anonymous · Answer

is there certain way to solve this problem

anonymous · Answer

On second thought. Are you sure the second equation shouldnt read $$x^2 +4y^2 = 16$$ Because i am getting imaginary numbers

anonymous · Answer

I was going to use the Elimination method but i am getting imaginary numbers when i do it that way.

anonymous · Answer

really

anonymous · Answer

the problem said

anonymous · Answer

solve the system: 
4x^2+9y^2=36
x^2-4y^2=16

anonymous · Answer

what are the imaginary numbers you are getting?

anonymous · Answer

$$\sqrt{\frac{28}{25}}i$$ I must be doing something wrong :/

anonymous · Answer

yea maybe because it said the answer has to be an ordered pair

anonymous · Answer

well you can write imaginary numbers in ordered pairs.. is this question in a math text book??

anonymous · Answer

or is it on a worksheet or something?

anonymous · Answer

its a computer program i have to do for homework

anonymous · Answer

how do you write imaginary numbers in an ordered pair?

anonymous · Answer

well thats what i was getting for the y value. So you would plug that into one of the original equations and solve for x and you would write it $$(x. \sqrt{\frac{28}{25}}i)$$ But finding x would be a pain and i dont think that Y value is right to begin with.
