Answer 2

Answer:

=> x = -7

Step-by-step explanation:

Given that:-

$7x + 9 = - 40$

To find:- The value of the expression,

In order to solve that, we have to use the concept of BODMAS:

As we know,

=> $7x + 9 = - 40$

Subtract both sides by $9$, we get

=> $7x + 9 -9= - 40-9$

=> $7x=-49$

Divide both sides by $7$,

=> x = -7

Hence, the required solution is -7.
