Question

Make x the subject. show work!

Answer 1

`x = (b)/(6a) - c`

Explanation:

Steps are as below:

(I will refer A as 'a' and B as 'b')

`a = (b)/(c + x) - 5a \\ a + 5a = (b)/(c + x) \\ 6a = (b)/(c + x) \\ 6a(c + x) = b \\ 6ac + 6ax = b \\ 6ac = b - 6ax \\ b - 6ax = 6ac \\ - 6ax = 6ac - b \\ 6ax = - (6ac - b) \\ 6ax = b - 6ac \\ x = (b - 6ac)/(6a) \\ x = (b)/(6a) - (6ac)/(6a) \\ x = (b)/(6a) - c`
