Answer 1

• 6x = 30 - 4x
• 6x + 4x = 30
• 10x = 30
• x = 30/10
• x = 3

Answer 2

Question ⤵️

$i}6x = 30 - 4x$

$\frac{x}{6} - \frac{2x}{7} = \frac{1}{21} + \frac{x}{7}$

Answer ⤵️

answer(i)⤵️

$6x + 4x = 30 \\ 10x = 30 \\ x = \frac{30}{10} \\ x = 3$

answer(ii)⤵️

$\frac{x}{6} - \frac{2x}{7} - \frac{x}{7} = \frac{1}{21} \\ \frac{7x - 12x - 6x}{42} = \frac{1}{21} \\ \frac{11x}{42} = \frac{1}{21} \\ 11x = \frac{42}{21} \\ 11x = 2 \\ x = \frac{2}{11}$
