x + 2y = 8
x2 + y2 = 52
Solve for x and y
congratulations @Onuora Chidera your money has been sent to your wallet.
Your first attempt, the process you took is a very long one and can hinder your success on that question.
You multiply equation 1 with two, where did you get that from?
I think you want to use Elimination method.
There is no 2 in equation II
You multiply equation I with any parameter in equation II and multiply equation II with any parameter in equation I to have the same value in either of the unknown variables so you can eliminate one.
@Isiaka Suarau once you solve any question, try and substitute the value you get into the equation and check if it will give you the exact value.
You got X to be 4 and Y to be 2
If you substitute that into equation 1 you will get 8 but if you substitute it into equation 2, you will get 20 which does not correspond with 52 given in the question
@Onuora Chidera Thank you for this explanatpry solution.
You got it right first.
X=4 and Y=2
