2 (5 - 8x) - 13 = 9 (1 - x) - 12
10 - 16x - 13 = 9 - 9x - 12
10 - 13 - 16x = 9 - 12 - 9x
- 3 - 16x = - 3 - 9x
- 3 + 3 = - 9x + 16x
0 = 7x
0/7 = x
0 = x

Irrational
Step-by-step explanation:
Square root if 12 is 3.464 and the square root of 3 is 1.732. You multiply 3.464 and 1.732 to get 5.99 which would be 6 if you round it up. The reason to why it's irrational is because 6 can not be written as a ratio of two integers, which means it cannot be expressed as a fraction.
