How would i solve for y and x in these equations, by elimination? x-5y=12 x-5y=7

Question

solving by elimination

Answer 1

Answer 2

To solve this by elimination you subtract both equations from each other!

So it would look like this:

x-5y=12

—(x-5y=7)

––––––––––

0 ≠ 5

The x's both cancel out and the 5y's also cancel out leaving us with a 0. 12 minus 7 gives us 5.

0 does not equal 5, therefore the answer is no solution!

Answer 3

Yes. Subtract (2) equations from the first. You will get 0=5

That mean NO SOLUTION
