#### Transcript of Two absolute value equations

Two absolute value equations
~ |2x+4| = 12

~ |x-5| = 3

Solving two absolute value equations
~ |2x+4| = 12 ~|x-5|=3
step 1. 2x+4=12 step 1. x-5 =3
step 2. -4 -4 (subtract 4) step 2. +5 +5 (add 5)
step 3. 2x=8 step 3.
step 4. 2x/2 = 8/2
step 5. x=4
Two absolute value inequalities
~ |-3x-1| > 5

~ |x+4| > 5
Solving two absolute value inequalities
Problem One
~ |-3x-1| > 5
Step 1. -3x-1 > 5
OR
Step 1. -3x-1 < -5
Step 2. +1 +1 (add 1) Step 2. +1 +1 (add 1)
Step 3. -3x > 6 Step 3. -3x < - 4
Step 4. -3x/-3 > 6/-3 Step 4. -3x/-3 < -4/-3
Step 5. x < -2 Step 5. x > 4/3
Solving two absolute value inequalities
Problem Two
~ |x+4| > 5
Step 1. x+4 > 5
OR
Step 1. x+4 < -5
Step 2. -4 -4 (subtract 4) Step 2. -4 -4 (subtract 4)
Step 3. x > 1 Step 3. x < -9
