Question

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

Answer 1

Y=3

y+3-3=-y+9-3

Simplify
y=-y+6

y+y=-y+6+y

2y=6

2y=6

2 2

y=3


I hope this helped!!

Answer 2

B. y = 3

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
