What ideas have you had so far?
First i tried to square everything, however could not continue to solve it after that.
Later on I tried to factorize the first two terms in both equations, but I could not do this. My third attempt was to divide every term my x and use the substitution method. The last try was to use the substitution method directly.
All my attempts gave an incorrect answer or I was not able to continue.
Can you please help me?
Thank you!
