Answer:
[tex]x=\frac{3}{4}[/tex]
Step-by-step explanation:
Whenever we have 2 fractions equal to each other, we first cross multiply, then take variables to one side and numbers to other side and use basic algebra to solve for the variable [here, it is x].
The process is shown below:
[tex]\frac{9}{16x}=\frac{3}{4}\\9*4=16x*3\\36=48x\\x=\frac{36}{48}=\frac{3}{4}[/tex]
So, x = 3/4
