It means you have to express y in terms of x.
in other words it means you have to re write the equation so that y is in one side and x and some other numbers should be in the other side.

Solve for x using the distributive property. 9(5 - x) = 81 x = [?]

Ilya [14]

Answer:

$\boxed {x = -4}$

Step-by-step explanation:

Solve for the value of $x$ :

$9(5 - x) = 81$

-Use Distributive Property:

$9(5 - x) = 81$

$45 - 9x = 81$

-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 $-4$ .
