Answer:
x=24
Step-by-step explanation:
Hi there!
We are given the following proportion:
![\frac{2}{10}=\frac{3}{x-9}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D%3D%5Cfrac%7B3%7D%7Bx-9%7D)
And we want to solve for x.
First, let's reduce
, as reducing fractions typically makes the process easier
is the same as ![\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D)
So:
![\frac{1}{5}=\frac{3}{x-9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B3%7D%7Bx-9%7D)
We can't do anything to
, but that's okay.
Now we can cross multiply, as this is a proportion
Multiply x-9 by 1 and 3 by 5
1(x-9)=3(5)
Multiply
x-9=15
Now this is an equation
Our goal is to isolate x on one side
So let's add 9 to both sides to remove it from the left side
x-9=15
+9 +9
_________
x=24
