7y:36x=12-4

To solve the equation \( 7y : 36x = 12 - 4 \), we can first simplify the right-hand side:

\[ 12 - 4 = 8 \]

So the equation can be expressed as:

\[ 7y : 36x = 8 \]

This indicates a ratio. We can write it as:

\[ \frac{7y}{36x} = 8 \]

To eliminate the fraction, we can cross-multiply:

\[ 7y = 8 \cdot 36x \]

This simplifies to:

\[ 7y = 288x \]

Next, if we want to isolate \(y\), we can divide both sides by 7:

\[ y = \frac{288}{7}x \]

Now, we have expressed \(y\) in terms of \(x\). If you have a particular task in mind (like finding specific values or further manipulating the equation), please let me know!
