\(\left(4,5-2x\right).1\dfrac{4}{7}=\dfrac{11}{14}\)

Answer 1

cái này đúng không nhỉ 

Answer 2

\(\Leftrightarrow4,5-2x=\dfrac{11}{14}:\dfrac{11}{7}\)

\(\Leftrightarrow4,5-2x=\dfrac{1}{2}\)

\(\Leftrightarrow2x=4,5-\dfrac{1}{2}\)

\(\Leftrightarrow x=4:2\)

\(\Leftrightarrow x=2\)

Answer 3

4,5 -2x = 11/14 : 1 4/7

4,5 -2x = 11/14 : 11/7

4,5 -2x =  1/2

2x = 4,5 - 1/2

2x = 4

x = 4 : 2

x = 2

Answer 4

(4.5-2x)x11/7=11/4

(chỗ 9/2 này me rút gọn nếu ko rút gọn thì là 45/10)->9/2-2x=11/4:11/7

9/2-2x=1/2

2x=9/2-1/2

2x=4

x=2

Answer 5

(4,5−2x).1và4/7=11/14

4,5 -2x = 11/14 : 1 4/7

4,5 -2x = 11/14 : 11/7

4,5 -2x =  1/2

2x = 4,5 - 1/2

x = 4 : 2

x = 2
