Answer 1

Answer:

no solutions

Step-by-step explanation:

3x - 6y= -12

x - 2y= -8

Solve the second equation for x

x-2y=-8

Add 2y to each side

x-2y+2y = -8+2y

x = -8+2y

Substitute this into the first equation every place to see x

3x-6y=-12

3(-8+2y) -6y=-12

Distribute the 3

-24 +6y -6y =-12

-24 = -12

Since this is never true there are no solutions.
