2x - 3 = 17 2x = 20 x = 10 dan 2x - 3 = 7 2x = 10 x = 5 f(2x - 3) = 4x - 7 f(17) = 4(10) - 7 = 33 . f(7) = 4 (5) - 7 = 13 ------------------------------ - ........f(17) - f(7) = 20..<-- jawaban atau 2x - 3 = p 2x = p + 3 x = (p+3)/2 f(2x - 3) = 4x - 7 f(p) = 4 [(p+3)/2] - 7 f(p) = 2 (p+3) - 7 f(p) = 2p + 6 - 7 f(p) = 2p - 1 f(17) = 2(17) - 1 = 33 ...f(7) = 2(7) - 1 = 13 --------------------------------- - ........f(17) - f(7) = 20..<-- jawaban Ok ?
