Solve the equation.

у + 3 = - у + 9

Оy = 1

Оy = 3

O y=6

Оy = 9

y=3

Step-by-step explanation:

y+3=-y+9

(3) + 3 = - (3) + 9

3+3=6

-3+9=6

6=6

So the answer will be B or y=3

y = 3

Step-by-step explanation:

Solve for y:

y + 3 = 9 - y

Add y to both sides:

y + y + 3 = (y - y) + 9

y - y = 0:

y + y + 3 = 9

y + y = 2 y:

2 y + 3 = 9

Subtract 3 from both sides:

2 y + (3 - 3) = 9 - 3

3 - 3 = 0:

2 y = 9 - 3

9 - 3 = 6:

2 y = 6

Divide both sides of 2 y = 6 by 2:

(2 y) / 2 = 6/2

2/2 = 1:

y = 6/2

The gcd of 6 and 2 is 2, so 6/2 = (2*3) / (2*1) = 2/2*3 = 3:

Answer: y = 3
