Hey there!
Negative 4 over 5 s: [tex] -\frac{4}{5}s [/tex]
equals 2: [tex]= 2 [/tex]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
First: Multiply both of your sides by [tex] \frac{5}{-4} [/tex]
Like: [tex] \frac{5}{-4} ( \frac{-4}{5})s \\ \\ \\ = \frac{5}{-4} (2) [/tex]
Cancel out [tex] \frac{5}{-4} ( \frac{-4}{5} s)[/tex]
Keep: [tex] \frac{5}{-4} (2)[/tex] because this will give you the outcome!
[tex]Answer: s = \frac{-5}{2} [/tex]
Good luck on your assignment and enjoy day!
