Answer 1

It's very simple to get answer of it.

$4x = 28$

$x = \frac{28}{4}$

$x = 7.$

Hence, the value of x is 7.

Answer 2

Answer:

• x = 7

Step-by-step explanation:

In this question we are given an equation that is 4x = 28 . And we have asked to find the value of x .

How to solve these types of equation ?

For solving such types of Equation basically equation having one variable we have to isolate the variable and then further solve them to find the value of given variable .

Solution : -

$\longmapsto \qquad \: 4x = 28$

For finding value of x , we need to isolate x . So , we are Dividing with 4 on both sides :

$\longmapsto \qquad \: \dfrac{ \cancel{4}x}{ \cancel{4}} = \cancel{ \dfrac{28}{4} }$

Now , by cancelling 4 with 4 on left side and dividing 28 by 4 on right side we get :

$\longmapsto \qquad \: \red{\underline{\boxed{\frak{x = 7}}}}$

• Henceforth , value of x is 7 .

Verifying : -

We are checking our answer by substituting value of x in given equation . So ,

• 4x = 28

• 4 ( 7 ) = 28

• 28 = 28

• L.H.S = R.H.S

• Hence , Verified .

Therefore, our value of x is correct .
