If x and y vary directly and y is 3 when x is 4, find y when x is 12.

Answer: Y is 9 when X is 12.

Step-by-step explanation:

Here is how you do it.

1. Make a table of x and y

x: 4,

y:3,

2. Keep continuing the table with list of numbers until x=12

x:4,8,12

y=3,6,9.

As you can see, when x is 12 y is 9.
