why did u times 2 n why did the 1/2 disappear ?
Left hand side x 2, right hand side must also x 2,
When right hand side x2, it cancel with ½.
i.e ½ × 2= 1
When right hand side x2, it cancel with ½.
i.e ½ × 2= 1

In equation, what you do at left hand side, you must do the same to right hand side. So it is equal.
why do u divide by 9
To get rid of 9 on right hand side.
In equation, if you want to find a unknown, for this question, a. So we leave "a" at one side, all other parameters move to another side or left hand side.
So we move 9, ½ and 13 to left hand side.
