Answer: x=12
Step-by-step explanation:
Equation:3|x-12|+7=7
Step 1: Add -7 to both side of the equation
3(|x−12|)+7+−7=7+−7(Cancels out)
=3(|x−12|)=0
Step 2: Divide both side of the equation by 3 to remove the 3
3(|x−12|)/3=0/3
=|x−12|=0
Step 3: Solve the absolute value
|x−12|=0 = x-12=0
x-12=0 ( Add 12 to both side of the equation)
x−12+12=0+12
Answer: x=12
