Question

How many posible solutions for x-3y=-3 and -2x+6y=12

Answer 1

there are no solutions

Explanation:

x-3y=-3

-2x+6y=12

multiply the first equation by 2

2( x-3y)=-3*2

2x-6y = -6

add the 2 equations together

2x-6y = -6

-2x+6y=12

-------------------

0 = -6

this is not true

so there are no solutions
