Step-by-step explanation:
<u>Step 1: Define</u>
-8 = 16x + 9
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 9 on both sides: -17 = 16x
- [Division Property of Equality] Divide 16 on both sides: -17/16 = x
- Rearrange/Rewrite: x = -17/16
<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>: -8 = 16(-17/16) + 9
- Multiply: -8 = -17 + 9
- Add: -8 = -8
Here we see that -8 does indeed equal -8.
∴ x = -17/16 is the solution to the equation.
