Answer 1

a)

$- 2(x - 3) + 3(2 - x) = x$

$- 2x + 6 + 6 - 3x = x$

$- 5x + 12 = x$

$- 5x - x = - 12$

$- 6x = - 12$

$x = 2$

b)

$3(x + 2) - 5(x - 1) = 3 - 6x$

$3x + 6 - 5x + 5 = 3 - 6x$

$- 2x + 11 = 3 - 6x$

$- 2x + 6x = 3 - 11$

$4x = 8$

$x = - 2$

c)

$3x - 5(x + \sqrt{2} ) = \sqrt{2} - 4x$

$3x - 5 - 5 \sqrt{2} = \sqrt{2} - 4x$

$- 2x - 5 \sqrt{2} = \sqrt{2} - 4x$

$- 2 x+ 4x = \sqrt{2} + 5 \sqrt{2}$

$2x = 6 \sqrt{2}$

$x = 3 \sqrt{2}$
