Step 1: Isolate the Variable
First, you want to get the term with x by itself. Start by subtracting 5 from both sides:
- 3x + 5 - 5 = 20 - 5
- This simplifies to: 3x = 15
Step 2: Solve for x
Next, divide both sides by 3 to solve for x:
- 3x / 3 = 15 / 3
- This gives you: x = 5
Final Answer
The solution to the equation 3x + 5 = 20 is x = 5.
