Given the specific gravities of two liquids and a specified specific gravity obtained upon mixing them, find the formula for calculating the amounts of the two liquids

I’m looking for the calculation formula; I hope some teacher can help me
No formula is needed for this; you can simply set up an equation or a system of equations to solve it. People these days have increasingly poor skills. You derived it yourself, and you’ll never forget the reasoning process for the rest of your life. Someone tells you the formula, and you forget it as soon as you use it. It is recommended to work it out by yourself; it will take no more than five minutes.
This is how I calculated it, and there may be a discrepancy with the actual usage, which is why I’m seeking help. Let’s go by the actual situation then, thanks
When two liquids are mixed, if the volume deviations are equal to the molar ratios, that is, under ideal conditions, the density of the mixture exhibits strict mathematical additivity. However, when most liquids are mixed together, the volume deviation is not ideal; that is, the volume after mixing is not equal to the sum of the individual volumes. As a result, the density value obtained from this addition is also not entirely ideal. Therefore, corrections need to be made based on actual conditions, or density curves for different mixing ratios should be created, keeping in mind that such curves are also affected by temperature. It is recommended that the original poster refer to the content on solution properties in physical chemistry.
