Solving Linear Equations

A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. The constants may be numbers, parameters, or even non-linear functions of parameters, and the distinction between variables and parameters may depend on the problem (for an example, see linear regression).

  • A linear equation is a polynomial of degree 1.
  • In order to solve for the unknown variable, you must isolate the variable.
  • In the order of operations, multiplication and division are completed before addition and subtraction.
  • Whatever you do to an equation, do the SAME thing to BOTH sides of that equation!
