Question

Solve each linear system. Vertify each solution by substituting the coordinates of your solution into both equations. The question I need help with is d)

Answer 1

Answer:a.(x,y) (3,-3)

b.(6,-2) c.(3,2)

Explanation:

Answer 2

x=3; y=3

Explanation:

y = -1/2 x + 9/2

so if we multiply by 2 on both sides

2y = -x + 9

and we know that y = 3x-6

so we get

2(3x-6)=-x+9

6x-12 = - x + 9

7x = 21

x = 3

y = 3 * 3 - 6

y=3

---

x=3, y=3

You put them in the equation and they should work.
