Problem solving consists of using generic or ad hoc methods, in an orderly manner, for finding solutions to problems.

The difference is that first you have to understand the problem and translate it into an equation (or equations).
An equation is a ploblem with no answer and an expression is a problem with an answer so you'll get different answers with an equation and an expression.
A line is represented by an equation. Each solution of the equation is a point on the line, and each point on the line is a solution to the equation. So the line is just the graph of the solution set of the equation.
Methods vary considerably depending upon the number of powers in the equation. For example, the method for solving cubics is quite different to solving quadratics etc... It's not really possible to generalise to one technique.
Converting the problem to an expression, equation, or in equality is an important step in solving the problem.5x+785>1,500
