hi i've got the question: solve the simultaneous equations $\displaystyle 2x + y = 9$ and $\displaystyle (x - 2)^2 + y^2 = 5$
can someone show me how this would be done please? thanks
Ouch! They were supposed to have covered this in class and in your text before assigning questions on it!
To learn "how this would be done", try an online lesson or two. Be sure to study the worked examples.
