If you would like to write the expression in math, you can do this using the following steps:
a number X ... X
12 times a number X ... 12 X
subtracted from 34 ... 34 -
is greater than eight ... > 8
34 - 12 X > 8
34 - 8 > 12 X
26 > 12 X /12
X < 26/12
X < 13/6
X < 2 1/6
The correct result would be X < 2 1/6.
