Question

\(\left(2x-4.5\right):\frac{3}{4}-\frac{1}{3}=1\)

Answer 1

<=>(2x-4,5):\(\frac{3}{4}\)= 1+\(\frac{1}{3}\)

<=> (2x-4,5):\(\frac{3}{4}\)=\(\frac{4}{3}\)

<=> 2x-4,5= \(\frac{4}{3}\).\(\frac{3}{4}\)

<=>2x-4,5= 1

<=> 2x= 1+4,5

<=>2x=\(\frac{11}{2}\)

<=>x= \(\frac{11}{2}\):2=\(\frac{11}{4}\)

Answer 2

 

(2x-4,5):3/4=1+1/3

(2x-4,5):3/4=4/3

2x-4,5=4/3.3/4

2x-4,5=1

2x=1+4,5

2x=11/2

x=11/2:2

x=11/4

Vậy x=11/4
