Question

Solve the following equation.

3(y + 8) = 10(y − 4) + 8

Solution

3(y + 8) = 10(y − 4) + 8

⇒ 3y + 24 = 10y - 40 + 8

⇒ 3y + 24 = 10y - 32

Adding 32 to both sides

⇒ 3y + 24 + 32 = 10y - 32 + 32

⇒ 3y + 56 = 10y

Subtracting 3y from both sides

⇒ 3y + 56 - 3y = 10y - 3y

⇒ 56 = 7y

Dividng both sides by 7 

⇒ `(7"y")/7 = 56/7`

⇒ y = 8

Hence, y = 8 is the solution of the equation.

  Is there an error in this question or solution?
