rezolvati in Q ecuatiile:
a)
[tex] \frac{4x + 7}{5} - \frac{3x + 2}{2} = \frac{4}{5} (3x - 4) - 1 \frac{1}{2} (x - 3)[/tex]
b)
[tex] \frac{3}{7} (x + 4) - \frac{2x + 9}{2 } = 1 \frac{1}{7} (x + 5) - 1 \frac{2}{3} (x + 3)[/tex]
c)
[tex]2 \frac{1}{5} - \frac{4(x + 1)}{3} + \frac{7x + 4}{5 } + \frac{2(x + 3)}{5} - \frac{2x + 5}{3} [/tex]
d)
[tex] \frac{ - 2(x + 5)}{6} + \frac{3(2x + 1)}{7} = \frac{ - 5(x + 1)}{14} + \frac{3x - 3}{21} [/tex]
