Answer:
No solutions
Step-by-step explanation:
4x + 2y = 2
2x + y = 4
we need to evaluate for y is "2x + y = 4" to be able to solve this.
2x + y = 4
2x - 2x + y = 4 - 2x
y = -2x + 4
4x + 2y = 2
4x + 2(-2x + 4) = 2
4x -4x + 8 = 2
8 = 2
NO solutions
Answer:
Step-by-step explanation:
Since he drives 60 miles per hour we'll divide 272 by 60
272/60=4.5
it will take 4.5 hours
I hope I've helped!
