  Solve Equation of One Variable

  To solve a linear equation isolate the variable, that is bring the variable to one side with arithmetic operations.

  Example:

  To solve ax+b=c use the following steps:

  1.ax+b=c, subtract b from both sides

  2.ax=c-b, divide both sides by a

  3.x=(c-b)/a

  Remember:

  All linear equations of one variable can be written as ax+b=c and the solution is x=(c-b)/a.
