Question #2: show my work

2x + 5y = 3
-2x - y = 5

x = -7/2, y=2

Step-by-step explanation:

2x + 5y = 3

-2x - y = 5

Add the two equations together to eliminate x

2x + 5y = 3

-2x - y = 5

     4y = 8

Divide each side by 4

4y/4 = 8/4

y =2

Now find x

2x +5y =3

2x +5(2) =3

2x+10 =3

Subtract 10

2x = -7

Divide by 2

2x/2 = -7/2

x = -7/2

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

i’m sorry but i don’t know sorry
