So i'm having trouble with simultaneous equations, the equations are: y^2 + x^2 = 150^2 3y + 2x = 180 Looks quite simple but i'm not sure where to get started mainly because of the '150^2'. Please help.

you can isolate (or x) from the second equation, so that then substitute it to the first equation, this is a quadric equation, hope you can solve it
