Given

The yellow line leaves the station every 6 min

The red line leaves the station every 8 min

They both leave at $4:15$

Both trains meet again after, LCM(6,8)=24 min

Solve the following Absolute Value Equation. Type the 2 solutions in the

klemol [59]

Answer:

-9, 15

Step-by-step explanation:

Subtract 7 and multiply by 4

1/4 |2x-6| +7 = 13

1/4 |2x -6| = 6

|2x -6| = 24

2x -6 = ± 24

2x = 6 ±24

x = 3 ±12

x = -9, 15

_____

For graphing purposes, it is often convenient to rewrite the equation so the solutions are where the function is zero. Here, we can do that by subtracting 13 from the equation.

(1/4 |2x -6| +7) -13 = 0
