"How many liters each of a acid solution and a 65% acid solution..."

What is the other acid solution? What concentration? You want a result of 45% acid but you want to mix two different acid solutions; you know one of them but not the other. The other acid solution must be lower than 45%. Are you only making a dilution of the 65% acid with water, or are you really planning for mixing TWO acid solutions? This makes a difference.

Assuming you have 65% and some other L% acids, and 0%3CL%3C65, and if you want u liters of L% and v liters of 65%, then you make equations:
%28Lu%2B65%29%2F50=45 and u%2Bv=50.
and you can solve the system for u and v. You still have no given value for L.
