  • An algebraic equation is made up of algebraic expressions separated by an equal sign. For example, \(2x-1=3+x\) is an equation, which shows that the algebraic expressions \(2x-1\) and \(3+x\) are equal. When the power of the variable in the equation is \(1\) then the equation is called a linear equation.

      Solve equations using inverse operations

      The "golden rule" of algebraic equations is, whatever you do to one side of the equation, you must do to the other side. The equation must be balanced at all times.

      So, if you add, subtract, multiply or divide on one side of the equation, you must do the same to the other side to keep the equation balanced. In the next video, solving equations using inverse operations to keep the equation balanced is explained.
