Answer:
The system consists of parallel lines, and the both lines have the same slope.
Step-by-step explanation:
The slope is the coefficient of x. (The coefficient of y should be 1)
When the slopes are equal, it means they are parallel.
20 key chains: 0.4x=50. Since they are parallel
You can do it in multiple ways but mine is.... 140+120-160=180
