Hi,
1.
[tex]5 + \frac{1}{7x} = 6 \\ 5 + \frac{6}{7x} \\ \frac{35x + 6}{7x} \\
5x+6\: \: \: \: < = \: result [/tex]
2.
[tex] \frac{z}{6} + 6 = 8 - \frac{z}{6} \\ \not6 \times \frac{z}{ \not6} + 6 \times 6 = 6 \times 8 - \not6 \times \frac{z}{ \not6} \\ z + 36 = 48 - z \\ z + z + 36 = 48 \\ z + z = 48 - 36 \\ 2z = 12 \: \: \: \: \: | \div 2 \\ z = 6[/tex]
Hope this helps.
