9+3|5-x|=24 What is the lines for and how do I solve X with them?

Ivahew [28]

Answer:

the lines represent absolute value bars

$x=0,10$

Step-by-step 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.

$x=0,10$
