\(\frac{3x+2}{5x+7}=\frac{5x-1}{5x+1}\)
\(\Leftrightarrow\left(3x+2\right)\left(5x+1\right)=\left(5x-1\right)\left(5x+7\right)\)
\(\Leftrightarrow15x^2+3x+10x+2=25x^2+35x-5x-7\)
\(\Leftrightarrow25x^2+30x-7-15x^2-13x-2=0\)
\(\Leftrightarrow10x^2+17x-9=0\)
.............
\(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
Tìm x , giúp mình nhé
a) \(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
b)\(\frac{x+1}{2x+1}=\frac{0.5x+2}{x+3}\)
tim x
\(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
\(\frac{x+1}{2x+1}=\frac{0.5x+2}{x+3}\)
tim x biet
a;\(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
b; \(\frac{x+1}{2x+1}=\frac{0,5x+2}{x+3}\)
Tìm x:
a, \(\frac{2x+3}{5x+2}=\frac{4x+5}{10x+2}\)
b,\(\frac{3x-1}{40-5x}=\frac{25-3x}{5x-34}\)
tìm x biết
a/\(\frac{3x}{7}=\frac{5x-1}{2}\)
b/\(\frac{2-5x}{3}=\frac{4+x}{5}\)
Tìm x trong tỉ lệ thức sau:
\(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
Trình bày giúp nha, ai nhanh mik T, cần gấp lắm
Giá trị của x trong tỉ lệ thức \(\frac{3x+2}{5x+7}=\frac{3x-1}{5x+1}\)
tim x \(\frac{3x+2}{5x+7}\)=\(\frac{3x-1}{5x+1}\)
