Answer:

(4,1)

3 x + 3 y = 15 - (-2 x + 3 y = -5)

3x + 3y = 15

2x - 3y = 5      +

____________

5x         = 20

x = 4

(3*4) + 3y = 15

12 + 3y = 15

3y = 15 -12

3y = 3

y = 1

Hoochie [10]

Answer:

We have been given an equation x^2+9x+20=0

We will factorize it by  middle term splitting.

Step 1: x^2+5x+4x+20=0

Taking common factors out by clubing first two terms ad last two terms

Step 2: x(x+5)+4(x+5)=0

Step 3: (x+4)(x+5)=0

Equating both above factors to zero as:

Step 4: (x+4)=0\Rightarrow x=-4

   And (x+5)=0\Rightarrow x=-5.
