Explain what happens when you try to solve this linear equation using an elimination strategy.

Question

What does this tell you about the graphs of these equations?
-8x + 20y = -40
24x - 60y = 120

Answer 1

-8x + 20y = -40 ----> 2x - 5y = 10
24x - 60y = 120 ----- > 2x - 5y = 12

Ahhh, I see two parallel lines, thus no solution

Answer 2

will it work if i write :

they have the same slope and are identical. Both have the slope of 2/5?

Answer 3

But they are not "identical" , their constants are different.
You have 2 different parallel lines

(think of railway tracks)
