-8x + 20y = -40 ----> 2x - 5y = 10
24x - 60y = 120 ----- > 2x - 5y = 12
Ahhh, I see two parallel lines, thus no solution
Explain what happens when you try to solve this linear equation using an elimination strategy.
What does this tell you about the graphs of these equations?
-8x + 20y = -40
24x - 60y = 120

will it work if i write :
they have the same slope and are identical. Both have the slope of 2/5?
they have the same slope and are identical. Both have the slope of 2/5?
But they are not "identical" , their constants are different.
You have 2 different parallel lines
(think of railway tracks)
