Solve for x using the<br> distributive property.<br> 9(5 - x) = 81<br> x = [?]
Ilya [14]

Answer:

\boxed {x = -4}

Step-by-step explanation:

Solve for the value of x:

9(5 - x) = 81

-Use <u>Distributive Property</u>:

9(5 - x) = 81

45 - 9x = 81

-Subtract 45 to both sides:

45 - 45 - 9x = 81 - 45

-9x = 36

-Divide both sides by:

\frac{-9x}{-9} = \frac{36}{-9}

\boxed {x = -4}

So, the value of x is -4.

Ilia_Sergeevich [38]

Answer:

3.5

Step-by-step explanation:

Please share the instructions next time.  I will assume that you want to solve -4.5 = a - 8 for a.  If that's the case, add 8 to both sides to isolate a:

8 - 4.5 = a, or

a = 3.5
