Answer:
c>9
Explanation:
To start off the problem, we don't normally like fractions when we deal with solving equations, so in order to get rid of it, we can multiply the entire problem by 3, to get the inequality of 2c+3>21 which looks a LOT simpler to solve!
From here, we can minus 3 from both sides to get the problem 2c>18. After this, we can divide both sides by 2 to get c>9!
(One side note that might help you out in the future is that if you ever need to multiply or divide both sides by a negative number, the inequality sign switches, for example if it was originally a < sign then it now turns into a > sign)
