Solve for X:   27 - X = (( 13 + 2 ) 5 - 6 ) / 3

Sure, let's solve this step by step:

1. First, simplify the expression in the inner parentheses: (13 + 2) = 15
2. So, the equation becomes: 27 - X = ((15)5 - 6) / 3
3. Next, perform the multiplication: 15 * 5 = 75
4. So, the equation becomes: 27 - X = (75 - 6) / 3
5. Then, perform the subtraction: 75 - 6 = 69
6. So, the equation becomes: 27 - X = 69 / 3
7. Then, perform the division: 69 / 3 = 23
8. So, the equation becomes: 27 - X = 23
9. Finally, solve for X by subtracting 27 from both sides: -X = 23 - 27
10. Simplify the right side: -X = -4
11. Multiply both sides by -1 to solve for X: X = 4
