Question

2x-3/3+-3/2=5-3x/6-1/3

tìm số hữu tỉ x

 

Answer 1

\(\frac{x}{2}-\left(\frac{3x}{5}-\frac{13}{5}\right)=-\left(\frac{7}{5}+\frac{7}{10}x\right)\)

\(\frac{x}{2}-\frac{3x}{5}-\frac{13}{5}=-\frac{7}{5}-\frac{7}{10}x\)

\(\left(\frac{1}{2}-\frac{3}{5}+\frac{7}{10}\right)x=-\frac{7}{5}+\frac{13}{5}\)

\(\frac{3}{5}x=\frac{6}{5}\)

\(x=2\)
