Answer»

Correct QUESTION:

✰ Three times a number 'm' subtracted from 8 is equal to -12.

To find:

✠ The value of m.

Solution:

LETS understand the concept first! Here, we are given that the three times a number 'm' which means 3 multiplied by the number 'm' i.e, 3 × m = 3m and the number is subtracted from 8 which means we will MINUS the number from 8 i.e, 8 - 3m is equal to - 1. Thus forming a requisite equation and doing the REQUIRED calculations, we will find out the value of m that is the required number.

Let's find out...✧

According to question,

➛ 8 - 3m = - 12

➛ - 3m = - 12 - 8

➛ - 3m = - 20

➛ m = -20/-3

➛ m = 20/3

∴ The value of m = 20/3

Verification:

L.H.S

➛ 8 - ( 3 × 20/3 )

➛ 8 - ( 1 × 20 )

➛ 8 - 20

➛ - 12

= R.H.S

Hence Proved!!
