Step-by-step explanation:
<u>Step 1: Define Equation</u>
6 - 4x = 7x - 9x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 6 - 4x = -2x - 6
- Add 4x on both sides: 6 = 2x - 6
- Add 6 on both sides: 12 = 2x
- Divide 2 on both sides: 6 = x
- Rewrite: x = 6
<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>: 6 - 4(6) = 7(6) - 9(6) - 6
- Multiply: 6 - 24 = 42 - 54 - 6
- Subtract: -18 = -12 - 6
- Subtract: -18 = -18
Here we see that -18 does indeed equal -18.
∴ x = 6 is the solution to the equation.
