-2t+1\geq t-20
Combine t and -3t to get -2t.
-2t+1-t\geq -20
Subtract t from both sides.
-3t+1\geq -20
Combine -2t and -t to get -3t.
-3t\geq -20-1
Subtract 1 from both sides.
-3t\geq -21
Subtract 1 from -20 to get -21.
t\leq \frac{-21}{-3}
Divide both sides by -3. Since -3 is negative, the inequality direction is changed.
t\leq 7
Divide -21 by -3 to get 7.
