=1.25 : 2.9 + 1/2
=25/58 + 1/2 =27/29

Học tốt!
3(x-2)-(x-2)=2(-5+x)-(x-2)
3(x-2)-(x-2)-2(-5+x)+(x-2)=0
3(x-2)-2(-5+x)=0
3x-6+10-2x=0
x+4=0
x=-4
Mk định ko tl nhưng thấy ''đề sai'' mk nghĩ bn sai chứ để x là PS ko sai
\(\frac{-2}{3}+\frac{x}{5}=\frac{1}{5}\)
\(\frac{-10}{15}+\frac{3x}{15}=\frac{3}{15}\)
\(-10+3x=3\)
\(3x=3-\left(-10\right)\Leftrightarrow3x=13\Leftrightarrow x=\frac{13}{3}\)
các bn ơi giúp mn bài này với

b: Ta có: \(\dfrac{x+2}{5}=\dfrac{3-2x}{11}\)
\(\Leftrightarrow11x+22=15-10x\)
\(\Leftrightarrow21x=-7\)
hay \(x=-\dfrac{1}{3}\)
2/5:5x2/5=2/5x1/5x2/5=4/125
