Step-by-step explanation:
<u>Step 1: Define</u>
6x + 4 = 5x + 17 + 120
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 6x + 4 = 5x + 137
- Isolate <em>x</em> terms: x + 4 = 137
- Isolate <em>x</em>: x = 133
<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(133) + 4 = 5(133) + 17 + 120
- Multiply: 798 + 4 = 665 + 17 + 120
- Add: 802 = 682 + 120
- Add: 802 = 802
Here we see that 802 does indeed equal 802.
∴ x = 133 is the solution to the equation.
