[tex] t= 50 + \frac{n - 4}{4} [/tex]
switch sides
[tex]50 + \frac{n - 4}{4} = t[/tex]
subtract 50 from both sides
[tex]50 + \frac{n - 4}{4} - 50 = t - 50[/tex]
simplify
[tex] \frac{n - 4}{4} = t - 50[/tex]
simplify
[tex] \frac{n - 4}{4} = t - 50[/tex]
multiply both sides by 4
[tex]4 \frac{(n - 4)}{4} = 4t - 4 \times 50[/tex]
simplify
[tex]n - 4 = 4t - 200[/tex]
add 4 both sides
[tex]n - 4 + 4 = 4t - 200 + 4[/tex]
[tex] n = 4t - 196[/tex]
