When solving for the value of x in the equation 4(x - 1) + 3 = 18,
aaron wrote the following lines on the board.
[line 1] 4(x - 1) + 3 = 18
[line 2] 4(x - 1) = 15
[line 3] 4x - 1 = 15
[line 4] 4x = 16
[line 5] x=4
which property was used incorrectly when going from line 2 to line 3?
(1) distributive (3) associative
