Since y = 12 we just plug that in for y 

12 = 3/4x 

And since 3/4 = 0.75 we will plug that in 

So our equation looks like this 
12 = 0.75x we first divide both sides by 0.75 
÷0.75 = ÷0.75 it cancels out on the right side and we solve on the left side. 

12 ÷ 0.75 = 16 
So..
When 
y = 12
then 
x = 16
