Question

Solve the following equation.

`("y" - 4)/3 +3"y"= 4`

Solution

`("y" - 4)/3 +3"y"= 4`

Multiplying both sides by 3

⇒ 3 `(("y" - 4)/3) + 3 (3"y") = 4 xx 3`

⇒ y - 4 + 9y = 12

⇒ 10y - 4 = 12

Adding 4 to both sides 

⇒ 10y - 4 + 4 = 12 + 4

⇒ 10y = 16 

Dividing both sides by 10

⇒ `(10"y")/10 = 16/10`

⇒ y = `8/5`

Hence, y = `8/5` is the solution of the equation.

  Is there an error in this question or solution?
