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