well they are the same values for x and y on the left... that equal different values on the right... 

it doesn't work...

I know that's why i'm confused

if it helps i'm doing a study guide for solving system of equation u elimination

anonymous · Answer

and substitution

its not possible because if you multiply both sides of one of the equations by -1 you get:

-1(-3x+6y)=-1(10) which equals
3x-6y=-10

so then you add them together (i cant remember the name of this method...) to be:
|dw:1385318880535:dw| 

and this is not possible because 0 does not equal 14
