What do you need to do? Solve for c?
yes, solve for c
Tell you what. If you don't like fractions, we'll just get rid of them. How? Here is how.
1/2 = 2/5(c) -3
multiply both sides by 2 (to get rid of the 1/2).
2*(1/2) = 2*(2/5)c - 2*3
1 = 4/5(c) - 6
Now multiply both sides by 5 (to get rid of the 5).
5*1 = 5((4/5)(c) - 5*6
5 = 4c - 30
can you take it from here?
