Solve the following equations Simultaneously:
y=x^3 and y=3x-2
My question is, how do I solve this? I've tried everything
The Attempt at a Solution
I've tried to isolate x in the linear equation and substitute it into the cubic. I don't know if that's wrong but it didn't work for me. This is what I did:
isolate x in linear equation: x= -2/3-y/3
substitute this into cubic equation: y=(-2/3-y/3)^3
I then expanded this and it didn't work.
I also tried: 3x-2=x^3
this didn't work either! please help!
