(x/10) - 5 = 75 == ==
It is not possible to answer the question because it is not clear what 75 is to be divided by.
To get the answer, you would divide both sides by 15 to get the variable (t) by itself. In which case, 75 divided by 15 would equal t. 75 divided by 15 is equal to 5, which means t=5.
