Best ResponseYou've already chosen the best response.0ok its like solving for x f(x) = 3x + 3 add 3x to both sides f(x) + 3x = 3x + 3x + 3 the tems in x disappear on right side 3x + f(x) = 3 now subtract f(x) from both sides 3x = 3  f(x) finally divide both sides by 3: x = (3  f(x)) / 3 replace f(x) by x and we have the inverse of f(x) f1 (x) = (3  x)/3
