1) 8c-(c-5)>c+17

How can I solve this??

1) 8c-(c-5)>c+17

How can I solve this??

we need to isolate the c's so

$\displaystyle 8c-c+5 > c+17$

subract c and 5 from both sides to get...

$\displaystyle 6c > 12$

divide both sides by 6 and we are done

$\displaystyle c > 2$

So our solution is all values of c greater than 2.
