Question

Can someone show me how to solve this? Thank you :)
How many solution does system?
-3x+6y=10
-3x+6y=-4

Answer 1

well they are the same values for x and y on the left... that equal different values on the right...

it doesn't work...

Answer 2

I know that's why i'm confused

Answer 3

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

Answer 4

and substitution

Answer 5

by*

Answer 6

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:


and this is not possible because 0 does not equal 14
