Question

Tìm x:

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

Answer 1

=>(2x-9/2):3/4=4/3

=>(2x-9/2)=1

=>2x=11/2

=>x=11/4

Answer 2

\(\left(2x-4,5\right):\dfrac{3}{4}-\dfrac{1}{3}=1\)

\(\left(2x-4,5\right):\dfrac{3}{4}=1+\dfrac{1}{3}\)

\(\left(2x-4,5\right):\dfrac{3}{4}=\dfrac{4}{3}\)

\(2x-4,5=\dfrac{4}{3}\times\dfrac{3}{4}\)

\(2x-4,5=1\)

\(2x=1+4,5\)

\(2x=5,5\)

\(x=5,5:2\)

\(x=2,75\)
