Answer 4

Giải

( 4,5 - 2x ) x \(\frac{11}{7}\)= \(\frac{11}{4}\)

( 4,5 - 2x ) = \(\frac{11}{4}\)x \(\frac{11}{7}\)

( 4,5 - 2x ) = \(\frac{7}{4}\)

             x = 4,5 -\(\frac{7}{4}\)

             x = 2 ,75.

Thử lại : ( 4,5 - 2,75 ) x \(\frac{11}{7}\)= \(\frac{11}{4}\)^0^.

Answer 5

<=>4,5-2x=11/4:11/7

<=>4,5-2x=4/7

<=>2x=4,5-4/7

<=>2x=55/14

<=>x=55/11:2

<=>x=5/2
