Which of these is a simplified form of the equation 7y + 7 = 9 + 2y + 2y?

3y = 2

7y = 6

11y = 16

4y = 16

The correct answer is A. 3y = 2

Step-by-step explanation:

The equation is given to be : 7y + 7 = 9 + 2y + 2y

We need to find the simplified form of the given equation

So, o find the simplified form, first separate the variable and constant to separate sides

⇒ 7y +  7 = 9 + 2y + 2y

⇒ 7y + 7 = 9 + 4y

⇒ 7y - 4y = 9 - 7

⇒ 3y = 2

Hence, This is the simplified form of the given expression

Therefore, The correct answer is A. 3y = 2
