Question

Tìm x:

6,28 x 12 - 174,62/x - 2 = 0,272 x 5

Answer 1

\(6,28\times12-\dfrac{174,62}{x}-2=0,272\times5\)

\(75,36-\dfrac{174,62}{x}=3,36\)

\(\dfrac{174,62}{x}=72\)

\(72x=174,62\)

\(x=2,425\)

Answer 2

Lời giải:

$6,28\times 12-\frac{174,62}{x-2}=0,272\times 5$

$75,36-\frac{174,62}{x-2}=1,36$

$\frac{174,62}{x-2}=75,36-1,36=74$

$x-2=174,62:74=2,36$

$x=2+2,36=4,36$
