3(3x + y = 1/3) ➡️ 9x + 3y =1

9x + 3y = 1 (3/3) Add together
2x - 3y = 8/3

11x = 11/3 divided by 11

x = 1/3

2x - 3y = 8/3 Find y

2(1/3) - 3y = 8/3 Plug in x

(2/3) - 3y = 8/3 Subtract 2/3
-2/3 -2/3

-3y = 6/3 Divided by -3

y = -2/3

(x , y) ➡️ (1/3 , -2/3)

Answer:

b) -10

Step-by-step explanation:

x^2 + 3x + k = (x - 2)(x - a)

(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a

-2 - a = 3

2a = k

a = -5

k = 2(-5) = -10
