Answer 2

Answer:

The required value of x$=-7$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question  - 3x - 5 = 16

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

Here we will use the transposition method.  

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

So, we will shift 5 from LHS to RHS the sign will change from negative to positive ,

As we get,

$-3x-5=16\\-3x=16+5\\-3x=21$

Dividing both side by -3 we get,

$\frac{-3x}{-3} =\frac{21}{-3} \\x=-7$

Hence we will get the value of x$=-7$
