Non-linear equations are:



Step-by-step explanation:
Lets define linear and non-linear first.
Linear equation is that equation whose degree is one. Degree is the highest power of a variable in an expression or equation.
Similarly, an equation with degree greater than 2 are called non-linear equation
In the given equations,
=> Degree: 3
=> Degree: 1
=> Degree: 2
=> Degree:1
=> Degree:2
Hence,
Linear equations are:


Non-linear equations are:
