Question

Solve the equation 3x = 12​

Answer 1

$\longrightarrow{\green{}}$ $3x = 12$

Divide both sides by 3.

$\longrightarrow{\green{}}$ $\frac{3x}{3} = \frac{12}{3}$

$\longrightarrow{\green{}}$ $x = 4$

Therefore, the value of $x$ is $\boxed{ 4 }$.

To verify:

$\longrightarrow{\green{}}$ $3 \times 4 = 12$

$\longrightarrow{\green{}}$ $12 = 12$

$\longrightarrow{\green{}}$ L. H. S. = R. H. S.

Hence verified.

Answer 2

Answer:

=> x = 4

Step-by-step explanation:

Given that:-

$3x = 12$

To find:- The value of the expression:

Here we will use the transposition method.

First of all, we have to identify the variables and the constants.

Then solve the expression of both sides by using various mathematical operations.

As we have,

=> $3x = 12$

Now, divide both sides by $3$ we get

=> $x = 4$

Hence, the required solution is 4.
