Princeton and Summitville are 320 miles apart. A train leaves Princeton heading toward Summitville at the same time a train leaves Summitville heading toward Princeton. One train is moving at a speed of 35 mph, and the other is moving 45 mph. How long will they travel before they meet?

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
