Answer 1

$a)$

$4(3x - 1) - 2(6 - x) = 5(1 - x) - 3(x - 5) \\ 12x - 4 - 12 + 2x = 5 - 5x - 3x + 15 \\ 14x - 16 = - 8x + 20 \\ 14x + 8x = 20 + 16 \\ 22x = 36 \\ x = 1 \frac{7}{11}$

$б)$

$(1.3x - 1.2)(4 + 8x) = 0 \\ \\ 1.3x - 1.2 = 0 \\ 1.3x = 1.2 \\ x = \frac{12}{13} \\ \\ 4 + 8x = 0 \\ 8x = - 4 \\ x = - 0.5$

$в)$

$\frac{x}{4} - \frac{1 - 2x}{9} - 2 = \frac{x - 9}{6} \\ \frac{9x - 4 + 8x - 72}{36} = \frac{x - 9}{6} \\ 54x - 24 + 48x - 432 = 36x - 324 \\ 102x - 456 = 36x - 324 \\ 102x - 36x = - 324 + 456 \\ 66x = 132 \\ x = 2$

$г)$

$|6x - 3| = |2x - 5| \\ \\ 6x - 3 = 2x - 5 \\ 6x - 2x = - 5 + 3 \\ 4x = - 2 \\ x = - 0.5$
