#### Question

Set up equations and solve them to find the unknown numbers in the following case

Munna subtracts thrice the number of notebooks he has from 50, he finds the result to be 8.

#### Solution

Let the number of books be x.

Thrice the number of books = 3x

50 - 3x = 8

-3x = 8 -50 (Transposing 50 to R.H.S.)

-3x = -42

Dividing both sides by -3

(-3x)/(-3) = (-42)/(-3)

x = 14
