Answer:

c > 9

Explanation:

To solve the inequality, we would have to get it into one of these four forms:

c > n

c < n

c ≤ n

c ≥ n

where n is a constant.

2c/3 + 1 > 7

Subtract 1 from both sides to remove the "+1" on the left side.

2c/3 > 7 - 1

Simplify.

2c/3 > 6

Multiply both sides by 6 to remove the "/3" on the left side.

2c > 6 · 3

Simplify.

2c > 18

Divide both sides by 2 to remove the coefficient of "2" on the left side.

c > 18/2

Simplify.

c > 9

c > 9 is in the form c > n, where n is 8. c > 9 would be the solution.

c > 9
