Answer 1

Heyyy mate !!!

Here is ur answer.

Answer 2

Answer:

=> X = 11

Step-by-step explanation:

Given that:-

$X + 9 = 20$

To find:- The value of the expression,  

For calculating the value of X, we have to apply the transposition method:

As we have,

=> $X + 9 = 20$

Now subtract both sides by $9$, we get

=> $X + 9 -9= 20-9$

Simplifying it further,

=> X = 20 - 9

Subtract the number,

=> X = 11

Hence, the required solution is 11.
