Question

7. Four times a number reduced by 5 Sequals 19 Find the number​

Answer 1

Answer:

6

Step-by-step explanation:

Let the number be x.

Then, 4x-5=19

or, 4x= 10+5

or, 4x= 24

or, x= 24/4

or, x= 6

Therefore, the number is 6.

Answer 2

Answer:

If the number is taken to be 'x'

Then four times of the number is '4x'

When it is reduced by 5 it equals to 19

⇒ 4x−5=19

4x=19+5 (Transposing −5 to RHS)

4x=24

∴ x=

4

24

(Transposing 4 to RHS)

⇒ x=6

Hence the required number is 6.
