\(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
\(\Rightarrow\left(3x+2\right)\left(5x+1\right)=\left(3x-1\right)\left(5x+7\right)\)
\(15x^2+10x+3x+2=15x^2-5x+21x-7\)
\(15x^2+10x+3x-15x^2+5x-21x=-7-2\)
\(-3x=-9\)
\(x=3\)

Tìm x , giúp mình nhé
Giá trị của x trong tỉ lệ thức \(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
tim x biet \(\frac{3x-1}{40-5x}\) = \(\frac{25-3x}{5x-34}\)
\(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
giúp mk vs , mk tik cho
