Question

solve the following linear equation in one variable 7x-4=31
​

Answer 1

$7x - 4 = 31$

$7x = 31 + 4$

$7x = 35$

$x = \frac{35}{7}$

$x = 5$

Hope it helps!

Answer 2

Answer:

=> The value of x is 5.

Step-by-step explanation:

Given that:-

$7x-4=31$

To find:- The value of the expression:

Here we will use the transposition method.

We have to follow these steps:-

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

( ii ) Get the variable to one side of the equation. Maintain equation balance while calculating.

( iii ) Then solve the expression of both sides by using various mathematical operations. Simplify both sides.

As we have,

=> $7x-4=31$

Add both sides by $4$, we get

=> $7x-4+4=31+4$

Simplifying it further, we get

=> $7x = 35$

Divide both sides by $7$, we get

=> $x = 5$

Hence, the required solution is 5.
