-2x - 13 = -3x - 5​

Step 1: Combine like terms

x's go with x's (-2x and -3x). To do this add 2x to both sides

(-2x + 2x) - 13 = (-3x + 2x) - 5​

(0) - 13 = (-x) - 5​

- 13 = -x - 5​

normal numbers go with normal numbers ( -13 and -5). To do this add 5 to both sides

(- 13 + 5) = -x + (- 5 +​ 5)

-8 = -x + (0)

-8 = -x

Step 2: Isolate x by dividing -1 to both sides (this will take the negative sign away from the x)

\frac{-8}{-1} =\frac{-x}{-1}

8 = x

x= 8

Hope this helped!

Let n =  the hours elapsed when the two trains are 660 miles apart.


Let the first train travel east and the second train travel west.

The distance traveled by the first train is

x = (50 mi/h)*(n h) = 50n mi


The distance traveled by the second train is

y = (60 mi/h)*(n h) = 60n h


The distance between the two trains after n hours is

x + y = 50 n + 60n = 110n mi


Because this distance is 660 miles, therefore

110n = 660

n = 6 hours


Answer: 6 hours


I hope this helps. Sorry it took so long
