a)
[tex] \frac{x}{3} + 1 = \frac{5}{6} + \frac{x}{2} | \times 6 \\ 2x + 6 = 5 + 3x \\ - x = - 1 \\ x = 1[/tex]
b)
[tex] \frac{2x - 3}{4} = \frac{1}{2} + x | \times 4 \\ 2x - 3 = 2 + 4x \\ -2x = 5| \div (-2) \\ x = -2.5[/tex]
c)
[tex] \frac{x + 2}{9} + \frac{x - 1}{3} = 1 | \times 9 \\ x + 2 + 3x - 3 = 9 \\ 4x = 10 | \div 4 \\ x = \frac{10}{4} = 2 \frac{2}{4} = 2.5[/tex]
