Answer 1

take -1/10 to the right side we get j =1.

Answer 2

• 
  `\tt j=1`

Explanation:

`\tt j-\cfrac{1}{10}=\cfrac{9}{10}`

Let's add 1/10 to both sides :-

• 
  `\tt j-\cfrac{1}{10}+\cfrac{1}{10}=\cfrac{9}{10}+\cfrac{1}{10}`

• 
  `\tt j= \cfrac{9}{10} +\cfrac{1}{10}`

Simplify :-

• 
  `\tt j=1`
