Answer: c > 12

Step-by-step explanation:tep 1 :

c

Simplify —

3

Equation at the end of step 1 :

c

((2 • —) - 1) - 7 > 0

3

Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 3 as the denominator :

1 1 • 3

1 = — = —————

1 3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2c - (3) 2c - 3

———————— = ——————

3 3

Equation at the end of step 2 :

(2c - 3)

———————— - 7 > 0

3

Step 3 :

Rewriting the whole as an Equivalent Fraction :

3.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 3 as the denominator :

7 7 • 3

7 = — = —————

1 3

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

(2c-3) - (7 • 3) 2c - 24

———————————————— = ———————

3 3

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

2c - 24 = 2 • (c - 12)

Equation at the end of step 4 :

2 • (c - 12)

———————————— > 0

3

Step 5 :

5.1 Multiply both sides by 3

5.2 Divide both sides by 2

Solve Basic Inequality :

5.3 Add 12 to both sides

c > 12

Inequality Plot :

5.4 Inequality plot for

0.667 X - 8.000 > 0

One solution was found :

c > 12
