thought this one was b but i don't think it goes to the second equation

anonymous · Answer

6x+6y=18
-2x-6y=2            4x = 20

anonymous · Answer

huh?

anonymous · Answer

i multiply the top by 3 and the bottom by -2 so i can eliminate the y leaves you with only the x

anonymous · Answer

multiply the first equation by 3 and the second equation by 2 
the first equation becomes : 6x+6y =18
the second equation becomes : 2x+6y= -2
on subtracting first equation from second : 4x=20 
                                                              => x=20/4 =5
=> x=5
