Hi Clever One,



Please help me with the following problem. I don't even know how to begin:-

Find the coordinates of the points of intersection of the line 2x+y = 5 and

The curve x^2+7y+2y^2=13.

Thanks,

Answer 1

Solve the equation of the line for y. Then take the value found for y and plug into 2nd degree equation. Now you should be able to solve this new equation for x.
