Tìm x biết 6060 . \(\frac{50.x+20}{x}\) = 101
6060:\(\frac{50.x+20}{x}\)= 101
\(6060:\frac{50x+20}{x}=101\)
\(\frac{50x+20}{x}=60\)
\(50x+20=60x\)
\(10x=20\)
\(x=2\)
\(6060:\frac{50x+20}{x}=101\)
\(\frac{50x+20}{x}=6060:101\)
\(\frac{50x+20}{x}=60\)
\(50x+20=60x\)
\(10x=20\)
\(x=2\)
\(60x-50x=20\)
Tìm x biết 6060 . 50.x+20/x = 101
6060 : ( (50 : x + 20) : x) = 101
giải chi tiết hộ em với ạ
em cảm ơn trước ạ
Tìm x
6060 . \(\frac{50x+20}{x}\)= 101
Tìm x
6060 : [( 50x + 20 ) : x ] = 101
tìm x
6060*50x+20/x=101
\(6060.\frac{50x+20}{x}=101\)
<=> \(\frac{50x+20}{x}=\frac{1}{60}\)
<=> \(3000x+1200=x\)
<=> \(2999x+1200=0\)
<=> \(x=-\frac{1200}{2999}\)

x-y 6060 : [(50x+20):x]=101
6060÷[(50x+20)÷x]=101
\(6060:\left[\left(50x+20\right):x\right]=101\)
\(\left(50x+20\right):x=60\)
\(50x+20=60x\)
\(60x-50x=20\)
\(10x=20\)
\(x=2\)
