Question

9x - 6=12 solve in linear equation ​

Answer 1

Given Expression :-

9x - 6 = 12.

How To Solve?

We will apply Transposition Method.

Transposition Method :-

It is a method to bring constants and variables to their respective sides but it requires change in signs.

Like :-

+ changes to -

- changes to +

× changes to ÷

÷ changes to ×

Solution :-

➠ $\sf{9x - 6 = 12}$

➠ $\sf{9x = 12 + 6}$

➠ $\sf{9x = 18}$

➠ $\sf{x = \dfrac{18}{9}}$

➠ $\boxed{\bf\red{x = 2 }}$

Answer 2

Answer:

=> x = 2

Step-by-step explanation:

Given that:-

$9x - 6=12$

To find:- The value of the x for the expression $9x - 6=12$,

By using the method of transposition,

As we have,

=> $9x - 6=12$

Add both sides by $6$,

=> $9x - 6+6=12+6$

Simplifying it further,

=> $9x=12+6$

Add the number on the right side,

=> $9x=18$

Divide both sides by $9$,

=> $x = 2$

Hence, the required solution is 9.
