Answer:
The value of y is 4.
Explanation:
First, you have the equation.
Subtract the 7 from both sides to reverse the additive 7 on the left side.
Then, you are left with this; 2y = 8.
Divide both sides by 2 to negate the two times y on the left side of the equation.
Then you are left with the answer; y = 4.
