Question:
Solve
10(n + 5) = 5n
Solution:
let the equation:
10(n + 5) = 5n
this is equivalent to
10n + 10(5) = 5n
this is equivalent to
10 n + 50 = 5n
this is equivalent to
10n - 5n = -50
this is equivalent to:
5n = -50
solve for n:
[tex]n\text{ = }\frac{-50}{5}=\text{ -10}[/tex]then, we can conclude that the correct answer is
n = -10
