Question

What is the answer to 3 over 20 = y over x ??

Answer 1

Answer: The equation is: 3x = 20y ; or, ↔ 20y = 3x ;
________________________________________________
x = 20y / 3 ;

y = 3x / 20 .

________________________________________________


`(3)/(20) = (y)/(x)` ;

_______________________________________
3x = 20y is the equation;
_______________________________________
To solve for "y" in terms of "x";
_______________________________________
20y = 3x ;
________________________________________
Divide EACH SIDE of the equation by "20" ; to isolate "y" on one side of the equation; and to solve for "y" in terms of "x" ;
________________________________________________
20y / 20 = 3x / 20 ;
________________________________________________
y = 3x / 20 ;
________________________________________________
To solve for "x" in terms of "y" ;
_________________________________________________
3x = 20y ;
__________________________________________________
Divide EACH SIDE of the equation by "3" ; to isolate "x" on one side of the equation; and to solve for "x" in terms of "y" ;
________________________________________
3x / 3 = 20y / 3 ;
______________________________________
x = 20y / 3 .
