Pls mark as brilliantist it will be a lot of help

here the explanation

Step-by-step explanation:

Let x be the number of books

We are given that Munna subtracts thrice the number of books she has from 50

⇒50 - 3x

He finds the result to be 8

So,50-3x=8

50-8=3x

42=3x

42/3= x

14=x

Hence he has 14 notebooks

Answer 2

Answer:

14 =x

Step-by-step explanation:

Let the required number be x.

Step I: 50 – 3x

Step II: 50 – 3x = 8 is the required equations.

Solving the equation, we have

50 – 3x = 8

⇒ -3x = 8 – 50 (Transposing 50 to RHS)

⇒ -3x = -42

⇒ −3−3=−42−3 (Dividing both sides by -3)

⇒ x = 14 is the required unknown number.
