STEP 1
Assumptions1. We are solving the absolute value equation |x-9|=4.
. The absolute value of a number is its distance from zero on the number line, and is always positive or zero.
3. The equation |x-9|=4 means that the distance between x and9 on the number line is4 units.
STEP 2
The absolute value equation |x-9|=4 can be rewritten as two separate equations, because the distance between x and9 can be4 units to the right or4 units to the left.
STEP 3
Now, we solve the first equation for x.
STEP 4
Add9 to both sides of the equation to isolate x.
STEP 5
Calculate the value of x.
STEP 6
Next, we solve the second equation for x.
STEP 7
Add9 to both sides of the equation to isolate x.
STEP 8
Calculate the value of x.
The solutions to the equation |x-|=4 are x=13 and x=5.
