[tex]3x+ \frac{4}{5}= \frac{7}{10} \\ \\3x= \frac{7}{10}-\frac{4}{5}\\ \\3x=\frac{7}{10}-\frac{8}{10}\\ \\3x=- \frac{1}{10} \ /:3\\ \\x=-\frac{1}{10}\cdot \frac{1}{3}\\ \\x=-\frac{1}{30}[/tex]

-------------------------------------------------

[tex] \frac{3x+4}{5} = \frac{7}{10} \\ \\10(3x+4)=5\cdot 7\\ \\30x+40=35\\ \\30x=35-40\\ \\30x=-5\ /:30\\ \\x=- \frac{5}{30} \\ \\x=-\frac{1}{6}[/tex]
