The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.
Select a number of different values for the independent variable (usually x). For each x, calculate the value of the dependent variable using the nonlinear equation. Call these f(x). On a Cartesian plane, mark the points whose coordinates are(x,f(x)) and join them by a smooth curve.

Twiddling your thumbs - certainly NOT a problem-solving step.

When you are solving an equation usually you are solving for x. If you want to check your answer just plug the values you got back in to the original function. Or you can use a different method to solve the equation and see if you get the same answer.
The first step is to solve one of the equations for one of the variables. This is then substituted into the other equation or equations.
By substitution or elimination of one of the variables which usually involves simultaneous or straight line equations.

Simultaneous equations are usually used in mathematics to find the values of three variables within a system.
No, linear equations don't have x2. Equation with x and y are usually linear equations. Equations with either x2 or y2 (but never both) are usually quadratic equations.
Substitution can occur in a great many different situations. Substitution usually occurs when someone is scheduled to teach for example and becomes sick.
Transcoding linear to nonlinear text is fairly straightforward. Nonlinear text usually refers to text with pictures. To transpose to linear text, simply remove the pictures and rewrite if necessary.
Usually not.
An operation usually used in solving equations which is the exact opposite of the original problem in order to isolate the variable. Addition and subtraction are inverse operations. Squaring and square roots are opposites. etc
Usually non-linear.Usually non-linear.Usually non-linear.Usually non-linear.
I usually find find nutmeg an acceptable substitute, but it depends on your purpose
