Answer 6

Ok, very nice. So you can multiply the denominator by 7 to get 2=21(c-18).

Answer 7

and then what do i do ?

Answer 8

divide ?

Answer 9

Yes to isolate c.

Answer 10

what do i divide ??

Answer 11

To isolate c you need to divide by 21 which gives (2/21)=c-18

Answer 12

it give me 0.0952380952381

Answer 13

That's what (2/21) equals in decimal form. So if you go back to the equation, (2/21)=c-18 to get c by itself you need to add 18 to both sides. Giving (380/21)=c
