Question

Tìm x 

4/2x-4=0,5

Answer 1

\(\frac{4}{2}x-4=0,5\)

=> \(\frac{4}{2}x=\frac{9}{2}\)

=> \(x=\frac{9}{4}\)

Answer 2

\(\frac{4}{2x}-4=0,5\)

\(\frac{4}{2x}=0,5+4\)

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

\(2x=4:4,5\)

\(2x=\frac{8}{9}\)

\(x=\frac{8}{9}:2=\frac{4}{9}\)

Vậy \(x=\frac{4}{9}\)

Answer 3

2x=4,5

x=2,25=2/1/4

Answer 4

4/2x - 4 = 0,5

2x = 4 + 0,5

2x = 4,5

x = 2,25
