ban nao tra loi dung minh tich cho

Answer 1

\(\left(x-3,52\right)\times3=21,42\)

\(\Rightarrow x-3,52=7,14\)

\(\Rightarrow x=7,14+3,52\)

\(\Rightarrow x=10,66\)

Answer 2

\(\left(x-3,5\right)\times3=21,42\)

\(\Rightarrow x-3,5=21,42:3=7,14\)

\(\Rightarrow x=7,14+3,5=7,64\)

Answer 3

X = 10, 66

Answer 4

a, ( x - 3,52 ) × 3 = 21,42

 x - 3,52 = 21,42 : 3

x - 3,52 = 7,14

x = 7,14 + 3,52 

x =10,66

Vậy x = 10,66
