if x% is Cl37, then
x*37 + (1-x)*35 = 35.453
x*37 + (1-x)*35 = 35.453

I want to be picky here. With the equation as stated, then x = FRACTION that is Cl 37 and 1-x = FRACTION that is Cl 35. If we want x% to be Cl 37, then the equation should be x*37 + (100 - x)*35 = 3545.3. This latter equation gives the percentage whereas the initial equation gives the fraction.
