Step-by-step explanation:

<u>Step 1: Define Equation</u>

2(6x + 4) - 6 + 2x = 3(4x + 3) + 1

<u>Step 2: Solve for </u><em><u>x</u></em>

Distribute: 12x + 8 - 6 + 2x = 12x + 9 + 1
Combine like terms: 14x + 2 = 12x + 10
Subtract 12x on both sides: 2x + 2 = 10
Subtract 2 on both sides: 2x = 8
Divide 2 on both sides: x = 4
