5c-3-3%261%2F2c%3C12

Change the mixed numbr 3%261%2F2 to 7%2F2

5c-3-expr%287%2F2%29c%3C12

Multiply every term on both sides by 2 to clear of fractions:

10c-6-7c%3C24

3c-6%3C24

add 6 to both sides:

3c%3C30

Divide both sides by 3

c%3C10

-------------------

10-+%28-7%29+%3C+-k%2F2+%2B2+%2B10

Change -(-7) to +7

10%2B7+%3C+-k%2F2+%2B2+%2B10

Combine 10+7 and 2+10

17%3C-k%2F2%2B12

Multiply every term on both sides by 2 to clear of fractions:

34%3C-k%2B24

Add k to both sides:

k%2B34%3C24

Add -34 to both sides

k%3C-10
