Question

Solve for x
x= _______

Answer 1

X=20 because in order for you to get a factor of 18 on the numerator you have to multiply by 2 and what ever you do to the top has to be done to the bottom.

Answer 2

x = 20

Explanation:

You want to solve for x the proportion ...

`(18)/(x)=(9)/(10)`

Solution

You can multiply both sides of this equation by 10x/9, and you will have ...

`(18)/(x)\cdot(10x)/(9)=(9)/(10)\cdot(10x)/(9)\\\\\\20=x`

The fraction equivalent to 9/10 with numerator 18 is 18/20. This tells us x=20.
