The first step for solving this equation is to distribute 3 through the parenthesis. 6y - 12 = 8y + 9 - 9y Collect the like terms with y. 6y - 12 = -y + 9 Move the variable to the left side and then change its sign. 6y + y - 12 = 9 Now move the constant to the right side and change its sign. 6y + y = 9 + 12 Add the terms on the left side of the equation. 7y = 9 + 12 Add the numbers on the right side. 7y = 21 Lastly,, divide both sides of the equation by 7 to find your final answer. y = 3 This means that y = 3 is the correct answer to your question.
