is 42. find The number​

Answer 1

Answer:-

The Required Number is 9.

Explanation:-

Given:-

• If 3 is subtracted from a number the result would be equal to 42.

To Find:-

• The Number.

So,

Let the Number be x.

Therefore ATQ:-

↦ (5 × Number) - 3 = 42.

↦ (5 × x) - 3 = 42.

↦ 5x - 3 = 42.

↦ 5x = 42 + 3.

↦ 5x = 45.

↦ x = 45/5.

↦ x = 9.

Therefore the Number is x which is equal to 9.

• Transportation method is the most common method to find out the value of unknown variable in such equations.

• In transportation method all known values are transported to one side (Mostly Right Side i.e. RHS) and unknown values to another side (Mostly Left side i.e. LHS).

• During this transportation (+) become (-) and vise-versa, (×) becomes (÷) and vise-versa.
