[tex]a) \frac{3x - 2}{5} - \frac{x - 7}{2} = \frac{2x}{5} + 3 \times \frac{4}{5} \\ \\ \ \\ b) \frac{x + 7}{9} - 1 \times \frac{1}{2} = \frac{x - 3}{2} \\ \\ c) \frac{1}{3} x - 5 = \frac{1}{2} (1 - x) - 3 \\ \\ d)3(x - 1) + 1 \frac{1}{2} = x + \frac{1}{2} \\ va \: rog \: ajutatima[/tex]

a)

[tex] \frac{6x - 4 - 5x - 45 - 4x - 40}{10} = 0[/tex]

-3x-89=0

-3x=89

x=-29,(6)

b)

[tex] \frac{2x + 14 - 9 - 9x + 27}{18} = 0[/tex]

-7x+32=0

×=4.57

c)

[tex] \frac{x - 30 - 3 + 3x + 9}{6} = 0[/tex]

4x-24=0

x=6

d)

[tex] \frac{6x - 6 + 3 - 2x - 1}{2} = 0[/tex]

4x-4=0

x=1
