Answer 1

Answer:

1/2-3x=0

1/2 = 3x

x = 1/6

check

1/2-3x=0

1/2 -3×1/6

1/2 - 1/2 =0

verified

Answer 2

Answer:

$\frac{1}{2} - 3x = 0 \\ \\ = > \frac{1 - 6x}{2} = 0\\ \\ = > 1 - 6x = 2 \times 0 \\ \\ = > 1 - 6x = 0 \\ \\ = > - 6x = - 1 \\ \\ = > 6x = 1 \\ \\ ( - \: and \: - \: cancelled) \\ \\ = > x = \frac{1}{6}$

$checking \: my \: answer \\ \\ \frac{1}{2} - 3( \frac{1}{6} ) = 0 \\ \\ = > \frac{1}{2} - \frac{3}{6} = 0 \\ \\ = > \frac{3 - 3}{6} = 0 \\ \\ = > \frac{0}{6} = 0 \\ \\ = > 0 = 0 \\ \\ hence \: verified$
