Give two possible values for each variable satisfying the given condition.​


A mathematical statement that indicates that the value of the LHS is equal to the value of the RHS is called an Equation.

Let us recall the matchstick pattern of the letter L. The number of matchsticks required for different number of Ls formed was given as 2 X n or 2n.

Here in this case, n is taken to be the number of Ls formed. Now for an example a student need to find out the number of Ls formed, knowing that the number of matchsticks needed is 10.

Hence we can write it as, 2n=10.

Here n is unknown. The value of “n” must be such that it should satisfy the condition above. This condition is called Algebraic equation. Hence that any equation like the above, is a condition on a variable .It is satisfied only for a definite value of the variable.

An equation has an equal sign (=) between its two sides. The equation says that the value of the left hand side (LHS) is equal to the value of the right hand side (RHS). If the LHS is not equal to the RHS, we do not get an equation. So hence to find out whether the given equation is an Algebraic Equation or not we have to check two things, an equation must have an equal sign (=) and a variable.

Solution of an Equation

The value of the variable in an equation which satisfies the equation is called a Solution to the Equation. So for example we take the equation 2n=10, If n = 1, the number of matchsticks is 2. Clearly, the condition is not satisfied, because 2 is not 10. We go on checking.
