First, to make everything easier,divide each side by 2 :

x = 2a + 2b

There's the solution for ' x '.

Now, if you want it solved for ' a ' , then subtract ' 2b ' from each side :

x - 2b = 2a

and divide each side by 2 : a = 1/2 (x - 2b)

and if you want it solved for ' b ' then subtract ' 2a ' from each side :

x - 2a = 2b

and divide each side by 2 : b = 1/2 (x - 2a) .
