Question

Tìm x biết : \(\frac{2x-1}{-3}=\frac{3x+2}{5}\)

Answer 1

x=-1/19

Answer 2

\(\frac{2x-1}{-3}=\frac{3x+2}{5}\)

\(\Leftrightarrow5\left(2x-1\right)=-3\left(3x+2\right)\)

\(\Leftrightarrow10x-5=-9x-6\)

\(\Leftrightarrow10x+9x=-6+5\)

\(\Leftrightarrow19x=-1\)

\(\Leftrightarrow x=-\frac{1}{19}\)

Answer 3

\(\frac{2x-1}{-3}=\frac{3x+2}{5}\)

\(\Rightarrow\left(2x-1\right).5=\left(3x+2\right).\left(-3\right)\)

\(\Rightarrow10x-5=-9x-6\)

\(\Rightarrow10x+9x=-6+5\)

\(\Rightarrow19x=-1\)

\(\Rightarrow x=\frac{-1}{19}\)

vậy \(x=\frac{-1}{19}\)
