1. x = 53
2. x = 6



maaf kalau salah
1 2/3 x 2 1/5 – X = 2
 5/3 x 11/5 –X = 2
 55/15- X =2
 X = 55/15 – 2
 X = 55/15 – 30/15
 X= 25/15 = 5/3
2 x (1/2 + X ) = 3
 2 x 1/2X = 3
 2 x X/2 = 3
 X/2 = 3/2 ( dikali silang ya)
 2X = 6, X=3
Untuk membedakan : x(kecil) = kali , X(besar) = x
(kalo ga salah)
