Question

Tìm x biết x . 4 - x : 4 - 24,76 = 190,48 : 2

Answer 1

x .4 - x : 4 - 24,76 = 190,48 : 2

x . 4 - x . 1/4 - 24,76 = 95,24

x .4 -x . 1/4 = 95,24 + 24,76

x .4 - x . 1/4 = 120 

x . [ 4-1/4]=120

x . 15/4 = 120

x = 120 : 15/4

x = 32

Answer 2

X.4-x:4-24,76=190,48:2 

X.4-x.1/4-24,76=95,24

X.4-x.1/4=95,24+24,76

X.4-x.1/4=120

X.(4-1/4)=120

X.15/4=120

X=120:15/14

X=32

Answer 3

X = 32 là đúng đó
