n = 2
distribute and simplify left side of equation
50 - 10n - 1 = 29
49 - 10n = 29 ( subtract 49 from both sides )
- 10n = 29 - 49 = - 20
n = [tex]\frac{-20}{-10}[/tex] = 2
To get rid of the parantheses we must multiply 10 by anything inside the parantheses.
10(5-n)-1=29
50-10n-1=29
Combine like terms
49-10n=29
Subtract 49 from both sides
-10n=-20
Divide both sides by -10
-10n/-10=-20/-10
n=2
Our final answer is 2
Hope this helps!
