Answer 2

Answer:

=> The value of x is 1.

Step-by-step explanation:

Given that:-

$2x + 7 = 9$

To find:- The value of x,

To solve this, we have to use the transposition method:  

As we have,

=> $2x + 7 = 9$

Subtract both sides by $7$, we get

=> $2x + 7-7 = 9-7$

Simplifying it further, we get

=> $2x = 2$

Divide both sides by $2$, we get

=> $x = 1$

Hence, the required solution is 1.
