2 tìm x : a) x nhân 4/5 : 2 = 6/7
b) 6/5 : x : 5/4 = 10/15
Tìm \(x\):

ai làm nhanh và đúng thì mình sẽ tích và likes
Tìm x :
a) x*4/5 : 2 = 6/7
b)6/5 : x : 5/4 =10/15
Giúp mik vs ạ! Ai đúng mik sẽ tick❤️👉🏻👈🏻
Câu 1: 200:(15 - x ) - 5 = 15. Câu2: 22- 63 :( x-5 ) = 1. Câu 3: 5/6 - ( 4/5 : x - 3/4 ) x 2/3 = 1/2 Câu 4 5/6 :10/9 + ( x nhân 2/3 - 3/5 ) : 2/5 = 5/4 câu 5 2/3 + ( 3/5 - 2/5 nhân x ) : 3/4 = 4/3 ..... Giúp mình nhé
