Explanation:
Step 1: Define equation
3x + 2 = 17
Step 2: Solve for x
- Subtract 2 on both sides: 3x = 15
- Divide 3 on both sides: x = 5
Step 3: Check
Plug in x into the original equation to verify it's a solution.
- Substitute in x: 3(5) + 2 = 17
- Multiply: 15 + 2 = 17
- Add: 17 = 17
Here we see that 17 does indeed equal 17.
∴ x = 5 is a solution of the equation.
