Answer 1

a)

$x - 4 = 3x + 2 \\ 3x - x = -2 - 4 \\ 2x = -6 \\ x = \frac{-6}{2} \\ x = -3$

b)

$x - 4 = 2 - x \\ x + x = 2 + 4 \\ 2x = 6 \\ x = \frac{6}{2} \\ x = 3$

c)

$4(x - 1) = 6(x - 3) \\ 2(x - 1) = 3(x - 3) \\ 2x - 2 = 3x - 9 \\ 3x - 2x = - 2 + 9 \\ x = 7$

d)

$1 - \frac{x}{4} = \frac{1}{2} \\ 4(1 - \frac{x}{4} ) = 4( \frac{1}{2} ) \\ 4 - x = 2 \\ x = 4 - 2 \\ x = 2$
