Answer:
approx. 3 hours
Step-by-step explanation:
14 newspapers in 20 minutes means he can deliver 42 newspapers an hour.
60/42 = 1.4285 newspapers per minute
131 x 1.4285 = 187.1335 minutes = 3.1188 hours
To solve this, you can substitute the second equation into the first.
It becomes 2x-(2x+3)=7
Solve from here!
You get -3=7. Not possible. Therefore there is no solution to this system.
System is inconsistent. Hope this helps.
