Question

Solve for c.

Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions.
55c+13≤75c+39

Answer 1

c≥-1.3

Explanation:

55c+13≤75c+39

subtract 13 from both sides

55c≤75c+26

subtract 75 from both sides

-20c≤26

divide by -20, the sign changes

c≥-1.3

Answer 2

-13/10 ≤ c

Explanation:

55c+13≤75c+39

Subtract 55c from each side

55c-55c+13≤75c-55c+39

13≤20c+39

Subtract 39 from each side

13-39≤20c+39-39

-26 ≤20c

Divide each side by 20

-26/20 ≤20c/20

-26/20≤ c

Divide top and bottom by 2

-13/10 ≤ c
