78 / 9 x 3 + (6 - 9)
78 / 3 + (-3)
26 - 3
23
Note that I did (1/9 * 3) first, due to the fact that 78/9 is not an integer, but 78/3 is.
(78/9)*3 = (78*3)/9 = 78*(3/9) = 78/3
78 / 3 + (-3)
26 - 3
23
Note that I did (1/9 * 3) first, due to the fact that 78/9 is not an integer, but 78/3 is.
(78/9)*3 = (78*3)/9 = 78*(3/9) = 78/3

Let's break down the problem step by step:
1. First, within the parentheses, we have 6 - 9 which equals -3:
78 / 9 x 3 + (-3)
2. Next, we perform the division: 78 divided by 9 equals 8.6667 (rounded to four decimal places):
8.6667 x 3 + (-3)
3. Then, we do the multiplication: 8.6667 multiplied by 3 equals 26 (rounded to the nearest whole number):
26 + (-3)
4. Finally, we add the numbers: 26 plus -3 equals 23.
Therefore, the solution to the equation 78 / 9 x 3 + (6 - 9) is 23.
