Answer 2

Answer:

=> a = 13

Step-by-step explanation:

Given that:-

$13 + 2a = 39$

To find:- The value of the x for the expression $13 + 2a = 39$,

By using the method of transposition,

As we have,

=> $13 + 2a = 39$

First of all, rearrange the terms:

=> $2a+13=39$

Subtract both sides by $13$,

=> $2a+13-13=39-13$

Simplifying it further,

=> $2a=26$

Divide both sides by $2$,

=> $a = 13$

Hence, the required solution is 13.
