abcdef=g solve for b
add gf to both sides of the equation.
abcd = g + ef
Now divide both sides of your equation by acd.
b = (g + ef)/acd
To solve for a letter means to isolate the letter on one side of the equation.

Isolate terms containg 'b'
abcd  ef = g ('f' does not have any terms containg 'b'  so it needs to be eliminated from Lefthandside)
abcd  ef + ef = g + ef
abcd = g + ef
Now you have to furthe "isolate" 'b' by dividing both sides by 'acd'
