Solve the equation 12=36y using substitution.

To solve the equation 12 = 36y using substitution, we need to solve for y.

We can start by dividing both sides of the equation by 36:

12/36 = (36y)/36

This simplifies to:

1/3 = y

Therefore, the solution to the equation 12 = 36y using substitution is y = 1/3.
