A student provided the following solution for solving an equation What mistake did the student make?
In the third line of the solution 3a should be
subtracted from each side instead of adding a to
each side
Original equation:
3(a - 2)+14 = 8-6
In the second line of the solution like terms were
combined incorrectly.
Solution: 3a - 2 + 14 =8-6a
3a + 12 = 8-60
9a + 128
9a --4
In the last line of the solution, the final answer
should be instead of -
4
9
In the first line of the solution, the distributive
property was applied incorrectly.
