@chrystaldenise :Got it ?:)
If got find y :)

anonymous · Answer

x=1

anonymous · Answer

nope still confuse

anonymous · Answer

First u should to know u want to find x or y ?
What do u want to find first ?:)

anonymous · Answer

i guess y

anonymous · Answer

K !
Now to find it we should kill the X s !

anonymous · Answer

for the first line i did4x-2y=-4
                                -4x    -4x
                                      -2y=-4x-4
                                        /-2=  /-2            y=-4x/-2 = 2   -4/-2 = 4

"using the graphing method"

This isn't using the graphing method.

Graph the two functions, and the points where they cross each other are solutions to the system of equations.

anonymous · Answer

so solve them both and than point the solutions
