Step-by-step explanation:
<u>Step 1: Define Equation</u>
6n + 7 = 55
<u>Step 2: Solve for </u><em><u>n</u></em>
- Subtract 7 on both sides:                    6n = 48
- Divide 6 on both sides:                       n = 8
<u>Step 3: Check</u>
<em>Plug in n into the original equation to verify it's a solution.</em>
- Substitute in <em>n</em>:                    6(8) + 7 = 55
- Multiply:                               48 + 7 = 55
- Add:                                     55 = 55
Here we see that 55 does indeed equal 55.
∴ n = 8 is a solution of the equation.
