6x+3y=24
3x-3y=-6
Solve the system using elimination (explain steps)

(x,y)=(2,4)

Step-by-step explanation:

⇒ 9x=18 divide both sides of the equation by 9

⇒ x=2

then put x=2 into the equation 3x-3y=-6

⇒ 3×2-3y=-6

⇒ 6-3y=-6

⇒ -3y=-6-6

⇒ -3y=-12

⇒ y=4

(x,y)=(2,4)

⇒

⇒

⇒ (x,y)=(2,4)

i believe the answer is the polygon, heptagon.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
