Answer 2

Answer:

We will get the value of x$=5$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question 14=7x− 21  

We have find the value of  x in  supplied expression in the above question.

Here we will use the transposition method.

Hence, for solving the above equation, we will solve it by separating the like terms at one side to another side  

So, we will shift 14 from LHS to RHS the sign will change from positive to negative,

So, we will shift 7x from RHS to LHS the sign will change from positive to negative,

As we get,

$14=7x-21\\-7x=-21-14\\-7x=-35$

Divide both side by 7 we get

$\frac{-7x}{7} =\frac{-35}{7} \\-x=-5$

$x=5$

Hence we get the value of x will be $5$
