15 - 4 1/3 = 10 2/3
10 2/3 * 3/5 = 6 4/10
10 2/3 - 6 4/10 = 4 4/15

Answer:
He added an unnecessary w and forgot to factor the 2
Step-by-step explanation:
Part A:
firs multiply 9 to 3x and minus 16, after that subtract 15 from -144, then add both side to 129, then subtract 6x from both side, at the end divide bothe side to 21, the answer is 5.
9(3x-16)+15=6x-24
27x-144+15 = 6x-24
27x-129 = 6x-24
27x = 6x -24 +129
27x = 6x +105
27x - 6x = 105
21x = 105
21x/21 = 105/21
x = 5
