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 :)
