Another algebra problem in two variables. Why are you changing names?

Please show your work for further assistance.

I'm not changing names. This is the only one that I posted today. Because this is the only one out of my homework that I don't understand how to do.

Let X = cc of 10% iodine solution

Let Y = cc of 15% iodine solution

X + Y = 20

(0.1X + 0.15 Y) = 0.12*20

X + 1.5 Y = 24

0.5Y = 4

Take it from there.
