0,5:x+0,4:x+0,1:x-0,25:x=0,75

Answer 1

[阮草~๖ۣۜDαɾƙ]

\(\left(0,5+0,4+0,1-0,25\right):x=0,75\)

\(0,75:x=0,75\)
\(x=1\)

Answer 2

[Toán học is my best:))]

\(\frac{1}{x}.\left(0,4+0,5+0,1-0,25\right)=\)\(0,75\)

\(\frac{1}{x}.0,75=0,75\)

\(\frac{1}{x}=1\)

\(1:x=1\)

\(x=1.1\Leftrightarrow x=1\)
