__Algebraic Equations and Solutions__

An **algebraic equation** is an equality involving variables. The expression on the left of equality is called **LHS (Left Hand Side)** and on the right is called **RHS (Right Hand Side)**.

- From the above example, an algebraic equation is 2x + 20 = 40, where x is variable. Here 2x + 20 is LHS and 40 is RHS.

A **Solution** is the true value of the variables in the algebraic equations for which the equation holds true and LHS is equal to RHS.

- From the above example, algebraic equation is 2x + 20 = 40.
- For x = 10, 2 * 10 + 20 = 40. Or, 40 = 40. Since LHS = RHS, hence x = 10 is the solution.
- For x = 5, 2 * 5 + 20 = 40.Or, 30 = 40. Since LHS ≠ RHS, hence x = 5 is not the solution.
