Question

Solve the equation below for c
a=b+c
-----
d

Answer 1

first multiply both sides by d and what do you get ?

Answer 2

I don't know how to do that.

Answer 3

ok, this is how
b+c
d . a = ------- . d
d

what is that equal to ?

Answer 4

C=ab+d

Answer 5

Maybe?

Answer 6

you have da = b+c (because when multiplying 1/d . d/1 you cancel the d on that side

Answer 7

now to isolate the c you subtract b as follows

da - b = b-b+c (b cancel on this side) and you have

da - b = c so c=da - b

Answer 8

or you can write as c = ad - b

Answer 9

Oh I get it now . Thanks!
