The error in the student's work first appears in line 3.
The student incorrectly simplified x minus 2 times 2x plus 1 to be 3x plus 2 in line 3, but the correct simplification should be -4x - 2. Then, solving for x, we get x = -1/2.
A student solved an equation, as shown below.
The first line shows 1 over 4 left Parenthesis 8 minus 12x right parenthesis equals x minus 2 left parenthesis 2x plus 1 right parenthesis, second line shows 2 minus 3x equals x minus 4x plus 2, third line shows 2 minus 3x equals 3x plus 2, fourth line shows 2 minus 3x plus 3x equals negative 3x plus 3x plus 2. Fifth line shows 2 equals 2.
