There you go! Hope that helps
Hi!
If we multiply the top equation by (-2), then we can cancel out the y's.
-2(2x + 5y = 15)
-4x - 10y = -30
Now we add the second equation and our new equation together, and get:
x = 5
Now, we plug this in to one of the other equations
2(5) + 5y = 15
distribute
10 + 5y = 15
subtract 10 from both sides
5y = 5
divide both sides by 5
y = 1
Therefore, your answer is (5, 1)
Have a great day! :D

Hello,
........|x^4|x^3|x^2|x^1|x^0
........| 1..|.2...|.-9.|.-2.|.8
x=-3.| ....|.-4..|.8..|.4..|.-8
........| 1..|.-2..|.-1.|..2.|.0
x^4+2x^3-9x^2-2x+8=(x+3)(x^3-2x^2-x+2)+0
-4 is a root of the polynomial expression.
