an nonlinear equation can be y=3x m dose not equal 7
A nonlinear equation does not produce a straight line and the exponent is to the second power or more. x square plus 3y =5 is an example of a nonlinear equation.
If you mean y = x2, then yes, it is nonlinear.
Without an equality sign the given expression is not an equation
In a nonlinear equation, each variable must only have one solution.
If you mean y = 2x then it is a straight line equation
