Question

Write the equation and solve : Two third of a number 'm' minus 7 gives 9

Answer 1

Answer -

The value of m is 24

Explaination :-

$= > \frac{(2m-21)}{3} \: = 9$

$= > 2 m - 21 = 27$

$= >2m = 27 + 21$

$= >2m = 48$

$= >m = 48/2$

$= > m = 24$

Answer 2

Welcome to the concept of linear equation, which is a part of algebra!

This is a question based on the concept of linear equation in one variable.

Here, we use variables and constants and the method of transposition to solve questions.

According to the question (ATQ):-

Two third of a number 'm' minus 7 gives 9.

=>2/3m-7=9

=>2/3m=9+7

=>2/3m=16

=>m=16×3/2

=>m=24

Verification:-

LHS=2/3m-7 RHS=9

2/3×24-7

16-7

9

So, LHS=RHS, hence verified
