# How do you solve 5(9-x)=4(x+18)?

Jul 5, 2018

$x = - 3$

#### Explanation:

On the left, we can distribute the $5$, and the right we can distribute the $4$. After doing this, we get

$45 - 5 x = 4 x + 72$

Next, let's subtract $45$ from both sides to get

$- 5 x = 4 x + 27$

Next, we can subtract $4 x$ from both sides to get

$- 9 x = 27$

Our last step would be to divide both sides by $- 9$. We get

$x = - 3$

Hope this helps!
