The easy thing to do is eliminate x by subtraction 
 
   x + 7y = 24
- x - 9y = -24
-------------------
      16y = 48

now solve for y and then substitute the value into either original equation to find x

Solve the equation. Use a calculator. c3 = 4 (Round to the nearest tenth as needed.)​

Two trains have to travel a distance of 300 miles. Train A goes at the speed of 50 mph and Train B goes at the speed of 60 mph.
sukhopar [10]

Answer:

Both trains would meet in 6 hours time.

Step-by-step explanation:

Train A = 50 miles per hour

Train B = 60 miles per hour

Train B leaves 1 hour later than Train A: This means Train A started the journey first.

When will the 2 trains meet?

Both trains would meet when they both cover equal distance.

Distance = Speed * Time

First Hour

Train A = 50 miles

Train B = 0 miles

Second Hour

Train A = 100 miles

Train B = 60 miles

Third Hour

Train A = 150 miles

Train B = 120 miles

Fourth Hour

Train A = 200 miles

Train B = 180 miles

Fifth Hour

Train A = 250 miles

Train B = 240 miles

Sixth Hour

Train A = 300 miles

Train B = 300 miles

Both trains would meet in 6 hours time.
