Question

Find the solution to the system of

equations.
You can use the interactive graph below to
find the solution.
8x - 4y = 16
8x + 4y = 16
X =
y =

Answer 1

Answer: x = + 1 y = -+ 2

Explanation:

Well what I did was input various values into both equations. I realized that if I could figure out what one of the values were I could get the other. So looking at the graph I though x = 1 so I entered into the equation and got that y could be either positive or negative 2 so there's the answers.

Answer: x = 1 y = +-2
