-20%3C=3t-2%3C1.......isolate the variable.... adding 2 to each expression, we get:
-20%2B2%3C=3t-2%2B2%3C1%2B2

-18%3C=3t%3C3.........divide by 3
-18%2F3%3C=3t%2F3%3C3%2F3
-6%3C=t%3C1.......the solution is all real numbers that are greater or equal to -6 and less than 1

check:
t=-6
-20%3C=3%28-6%29-2%3C1
-20%3C=-18%3C1
