Answer:
Amount of  vinegar. 100% : 20 milliliters
Amount of  Italian dressing: 140 milliliters
Step-by-step explanation:
Let's call A the amount of  vinegar. 100% 
Let's call B the amount of  Italian dressing . 12% vinegar
The resulting mixture should have 23%  vinegar, and 160 milliliters.
Then we know that the total amount of mixture will be:

Then the total amount of pure antifreeze in the mixture will be:


Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation:


                +

--------------------------------------



We substitute the value of B into one of the two equations and solve for A.
