-3/4t-8>-5t+5
-3/4t-8>-20/4t+5
Add 20/4t from both sides:
17/4t-8>5
Add 8 from both sides:
17/4t>13
Divide 4/17 from both sides:
(4/17)(17/4)t=(4/17)13
t>52/17

Check:
(-3/4)(52/17)-8=-5(52/17)+5
-39/17-136/17=-260/17+85/17
-175/17=-175/17

I hope this helps!

-3/4t+5t-8>-5t+5t+5
17/4t-8+8>5=8
17/4t>13
Multiply both sides by 4/17

t>52/17
t>3 1/17
