✼ Answer
➺ Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air. You hang up a wet towel and, when you come back, it's dry.

★ There is a person who bought three pens and two pencils together and he paid Rupees 80 for that, we have to express this situation in the form of linear equation. Let us solve this question!

★ A person bought 3 pens and 2 pencils together and paid Rupees 80. Expressing in the form of linear equation is 3a + 2b = 80

★ Let number of pen be 3a
★ Let number of pencil be 2b

~ As we already assume that
Number of pen as 3aNmber of pencil as 2b
And according to the question, it is said that person paid Rupees 80 for there together means sign of addition is about to use here. Henceforth,
3a + 2b = 80
A person bought 3 pens and 2 pencils together and paid Rupees 80. Expressing in the form of linear equation is 3a + 2b = 80.

❶ Linear equation: Here we will have to deal with linear expressions in just one variable. Such equations are known to be "linear equation in one variable"
❷ An algebraic equation in an equality involving variable. It has an equality sign. The expression on the left of equality sign is LHS. The expression on the right of equality sign is RHS like in the expression 2x - 3 = 7
↦ 2x is variable
↦ = is the sign of equality
↦ 7 is equation
↦ 2x - 3 is LHS
↦ 7 is RHS.
❸ In an equation the values, of the expression on LHS and RHS are equal. This happen to be true ! for certain values of that variable. The values are the solution of that equation like,
↦ x = 5 is the solution of the equation
↦ 2x - 3 = 7 [ x = 5 ]
↦ LHS = 2 × 5 - 3 = 7 = RHS
↦ On the other hand, x = 10 is nor a solution of the equation [ x = 10 ]
↦ LHS = 2 × 10 - 3 = 17
↦ This isn't equal to the RHS.
❹ How to find solution for equation?
★ We have to assume that the 2 sides of the equation are in a balance. We have to perform the same mathematical operation on both sides of the equation so that the balance isn't disturbed
