Solve the system by adding or subtracting: -3x-3y=9 3x+8y=6

x=-6,  y=3

Step-by-step explanation:

I will use elimination to eliminate the x variable.

Add the two equations.

-3x-3y=9

3x+8y=6

   5y  = 15

Divide each side by 5

5y/5 = 15/5

y=3

Now we need to find x

3x+8y=6

Substitute y=3

3x+8*3 =6

3x+24=6

Subtract 24 from each side

3x+24-24 = 6-24

3x = -18

Divide each side by 3

3x/3 = -18/3

x=-6

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
