Is 3x plus 2y equals 15 and 6x plus 4y equals 30 Consistent or inconsistent?

We will see.
3X + 2Y = 15
6X + 4Y = 30
I do not like the look of elimination, so substitution
3X + 2Y = 15
3X = 15 - 2Y
X = 5 - 2/3Y
--------------
6(5 - 2/3Y) + 4Y = 30
30 - 12/3Y = 30
30 - 4Y = 30
this is inconsistent in approach
3(5 - 2/3Y) + 2Y = 15
15 - 15/3Y = 15
another bad approach, try elimination to show inconsistency
- 2(3X + 2Y = 15)
6X + 4Y + 30
-6X - 4Y = - 30
6X + 4Y = 30
I think it is safe to say these systems of equations are
inconsistent

Is 2x-y equals 15 and 2x plus 3y equals -21 consistent or inconsistent?
2x - y = 15 2x + 3y = -21 As you observe both equations (having different slopes), you see that the system is consistent, and it has only one solution.
