Step-by-step explanation:
<u>Step 1: Define Equation</u>
-(5 - 8x) + 4x = -89
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute negative: -5 + 8x + 4x = -89
- Combine like terms: -5 + 12x = -89
- Isolate <em>x</em> term: 12x = -84
- Isolate <em>x</em>: x = -7
<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>: -(5 - 8(-7)) + 4(-7) = -89
- Multiply: -(5 + 56) - 28 = -89
- Add: -61 - 28 = -89
- Subtract: -89 = -89
Here we see that -89 does indeed equal -89.
∴ x = -7 is the solution to the equation.
