Algebraic Equation
An algebraic equation is a mathematical expression with two expressions equal to each other. The algebraic equation of the above example,
4x – 7 = 1 or
4x – 7 = 5
The statement on the left-hand side equals the statement on the right-hand side. A basic difference between an algebraic expression and algebraic equation it the ‘=’ operator.
