Answer:
[tex]\boxed {x = -4}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]9(5 - x) = 81[/tex]
-Use Distributive Property:
[tex]9(5 - x) = 81[/tex]
[tex]45 - 9x = 81[/tex]
-Subtract [tex]45[/tex] to both sides:
[tex]45 - 45 - 9x = 81 - 45[/tex]
[tex]-9x = 36[/tex]
-Divide both sides by:
[tex]\frac{-9x}{-9} = \frac{36}{-9}[/tex]
[tex]\boxed {x = -4}[/tex]
So, the value of [tex]x[/tex] is [tex]-4[/tex].
