Question

Solve d=a+c/ac for a

Answer 1

a=d(ac)-c

Explanation:

Yes (multiply ac both sides subtract C both sides gets a alone)

Answer 2

`d = (a + c)/(ac) \\`

multiply either sides by ac :

`(d * ac) = ( (a + c)/(ac) ) * ac \\ \\ dac = a + c`

collect a - terms together, by subtracting a from both sides:

`dac - a = (a + c) - a \\ dac - a = c`

factorise out a :

`a(dc - 1) = c \\ \\ { \boxed{ \boxed{a = (c)/(dc - 1) }}}`
