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