y=x2 and y=lnx are two examples of nonlinear equations.
a straight line
Isolating a variable in one of the equations.
In general, a system of non-linear equations cannot be solved by substitutions.
One can solve equations of motion by graph by taking readings of the point of interception.
A system of equations means that there are more than one equations. The answer depends on the exact function(s).
y=x2 and y=lnx are two examples of nonlinear equations.
