Question

Solve the following equation.

`("b" + ("b" + 1) + ("b" + 2))/4 = 21`

Solution

`("b" + ("b" + 1) + ("b" + 2))/4 = 21`

Multiplying both sides by 4

⇒ 4 x `("b" + ("b" + 1) + ("b" + 2))/4 = 4 xx 21`

⇒ b + (b + 1) + (b + 2) = 84

⇒ 3b + 3 = 84

Subtracting 3 from both sides

⇒ 3b + 3 - 3 = 84 - 3

⇒ 3b = 81

Dividing both sides by 3

⇒ `(3"b")/3 = 81/3`

⇒ b = 27

Hence, b = 27 is the solution of the equation.

  Is there an error in this question or solution?
