Class 6 Chapter 9: Algebraic Equations

Important Concepts and Formulas

1.      An equation is a statement of equality between two expressions.

2.      An equation has two sides separated by the symbol (=). The two sides are LHS and RHS.

3.      A solution of an equation is a numerical value, which when substituted for the variable in the equation makes the equation true.

4.      There are different methods for finding the solution of an equation. To solve an equation in one variable, we can

·        add the same number to both sides.

·        subtract the same number from both sides.

·         multiply both sides by the same number.

·         divide both sides by the same (non-zero) number.

5.      The concept of algebraic equation can be utilized to solve problems related to real-life situations.
