Question

X + 4y = 23
-3x = 12y + 1
is it no solution?

Answer 1

Answer: Yes

Explanation:

First multiply the first equation by three to get 3x+12y=69

Then subtract 12y from both sides of the second equation

Then add the first system and the second like this:

`3x+12y=69\\-3x-12y=1\\--------\\0+0=70\\0=70`

Because 0≠70, the system has no solutions
