Answer:
[tex]S = \frac{6}{7}N - 23[/tex]
Step-by-step explanation:
[tex]N = \frac{7}{6}S + 23[/tex]
Start by subtracting 23 from both sides
[tex]N - 23 = \frac{7}{6}S[/tex]
when we have a fraction we can always multiple both sides with its reciprocal
[tex](\frac{6}{7}) * N - 23 = \frac{7}{6} * (\frac{6}{7}) S[/tex]
7/6 and 6/7 on the right side will equal to 1
[tex]S = \frac{6}{7}N - 23[/tex] or [tex]S = \frac{6N}{7} + \frac{138}{7}[/tex]
