First, please do not use all capitals. Online it is like SHOUTING. Not only is it rude, but it is harder to understand. Thank you.

Let x = # of white and y = # of yellow.

x = 18 -y

9.95x + 11.5y = 202.35

Substitute 18-y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
