Solve the equation.
y + 3 = -y + 9
A. y = 1
B. y = 3
C. y = 6
D. y = 9

B. y = 3

Step-by-step explanation:

to solve the equation, you need to get y by itself. so, you have to add y to both sides, then subtract 3 from both sides. after that, you divide both sides by 2 and there's your answer.

it'll look like this:

  y + 3 = -y + 9

     2y + 3 = 9

        2y = 6

           y = 3
