Step-by-step explanation:
<u>Step 1: Define equation</u>
3x - 5 = 9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 5 to both sides: 3x = 14
- Divide 3 on both sides: x = 14/3
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 3(14/3) - 5 = 9
- Multiply: 14 - 5 = 9
- Subtract: 9 = 9
Here we see that 9 does indeed equal 9.
∴ x = 14/3 is a solution of the equation.
