Simplify it by getting the variable t on one side of the inequality alone and everything else on the opposite side.
The variable t is being multiplied by 3. Reverse the operation by dividing both sides of the inequality by 3.
3t / 3 > 6 / 3
t > 2
To be in the solution set, t has to be greater than 2.
Or in interval notation: (2, ∞)
Or in a set builder notation: t
