Question

Tìm x biết 

X . 4 - X : 4 - 24,7 = 190,48 : 2

Answer 1

\(x.4-x:4-24,7=190,48:2\)

\(x.4-x.\frac{1}{4}-24.7=95.24\)

\(x.\left(4-\frac{1}{4}\right)-24,7=95,24\)

\(x.\frac{15}{4}=95,24+24,7\)

\(x.\frac{15}{4}=119,94\)

\(x=119,94:\frac{15}{4}\)

\(x=31,984\)

Vậy \(x=31,984\)

Answer 2

                 Giải

X.4-X:4-24,7=190,48:2

X.4-X.1/4-24,7=95,24

X.(4-1/4)=95,24+24,7

X.15/4=119,94

X=119,94:15/4

X=31,984

Vậy X=31,984
