Homework Equations
If a(y+z)=x, b(z + x)=y, c(x+y)=z, prove that x2/a(1-bc) = y2/b(1-ca) = z2/c(1-ab)
The Attempt at a Solution
ay+az=x,bz+bx=y,cx+cy=z.
i solved these equations and found x,y and z values,pluged them onto the proof equation.but it took me about half an hour for that.is there a quicker or easier way to approach these kind of questions?
