The incorrect solution is B.
In solution B, the equation is set up incorrectly. The sum of the two adjacent angles should be equal to 180 degrees, so the equation should be "4x - 2 + 3x + 6 = 180". However, the equation given in solution B is "7x + 4 = 180", which is incorrect. Therefore, solution B is the incorrect solution.

Which solution for the value of x in the figure below is incorrect? Explain.
GEOA_03_L10_Q17
The angle adjacent below the top parallel line and adjacent right to the transversal is labeled left parenthesis 4 x minus 2 right parenthesis degrees.
The angle adjacent above the lower parallel line and adjacent left to the transversal is labeled left parenthesis 3 x plus 6 right parenthesis degrees.
A. 4x – 2 = 3x + 6 B. 4x – 2 + 3x + 6 = 180
x = 8 7x + 4 = 180
x = 25.1
