How do you solve for y in the problem 9 = -y

y = -9

Step-by-step explanation:

1. Divide -1 from both sides

2. Answer is y = -9

y=-9

Step-by-step explanation:

If a variable is by itself then the coefficient is always 1. Think of is as an imaginary 1. In this case since there is a negative in front of the variable it is -1. Then, you divide each side by -1. A positive divided by a negative equals a negative. y=-9

Example: -y=10

-y/-1 =y

10/-1= -10

Therefore, y=-10

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
