Solve the following equation.
`("b" + ("b" + 1) + ("b" + 2))/4 = 21`
उत्तर
`("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.
