I thought this problem was pretty easy, but I couldn't figure out the last step.
16 ( t - 1 ) + 10 > 8 ( t + 2 ) + 4 ( t -1 ) + 4t
Here is what I did, but I don't know if it is right.
16t - 16 + 10 > 8t + 16 + 4t - 4 + 4t distribute
16t - 6 > 16t + 12 simplify
16t - 6 + 6 > 16t + 12 + 6 add
16t > 16t + 18
16t / 16 > (16t + 18)/ 16 divide
t > t + 1.125 <-----Is that possible?

What do I do next? Did I do somthing wrong?

Your steps are correct.

Your conclusion should be - no solution
