Key Insights
Step 1: Understand the Equation
You start with the equation:
3x + 6 = 54
This means “three times an unknown number x, plus six, equals fifty-four.”
Step 2: Eliminate the Constant on the Left Side
To isolate the term with x, subtract 6 from both sides:
3x + 6 – 6 = 54 – 6
Simplify:
3x = 48
This step removes the constant, keeping the equation balanced—a key math principle.
Step 3: Isolate the Variable
Now, divide both sides by 3 to solve for x:
3x ÷ 3 = 48 ÷ 3
Simplify:
x = 16
