Answer:

the lines represent absolute value bars


x=0,10

Explanation:

STEP 1: Move all terms not containing |5−x| to the right side of the equation.


3|5-x|=15

STEP 2: Divide each term by 3 and simplify.


|5-x|=5

STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.

5-x=±5

STEP 4: Set up the positive portion of the ± solution.


5-x=5

STEP 5: Solve the first equation for x.


x=0

STEP 6: Set up the negative portion of the ± solution.


5-x=-5

STEP 7: Solve the second equation for x.


x=10

NOTE: The solution to the equation includes both the positive and negative portions of the solution.


x=0,10
