Question

Solve the following equation.

`"y"/7 + "(y-4)/3 = 2`

Solution

`"y"/7 + "(y-4)/3 = 2`

Multiplying both sides by 21

⇒ 21 `("y"/7)` + 21 `("y" - 4/3)` = 2 x 21

⇒ 3 `("y")` + 7 `("y" - 4)` = 42

⇒ 3y + 7y - 28 = 42

⇒ 10y - 28 = 42

Adding 28 to both sides

⇒ 10y - 28 + 28 = 42 + 28

⇒ 10y = 70

Dividing both sides by 10

⇒ `(10"y")/10 = 70/10`

⇒ y = 7

Hence, y = 7 is the solution of the equation.

  Is there an error in this question or solution?
