A tea that is 24% jasmine is blended with a tea that is 14% jasmine. How many pounds of the 24% jasmine tea are used to make 10 lbs of tea that is 17% jasmine?

I am having trouble knowing how to turn this into an equation. I could solve it if it was an equation. How do I do this?

I ended up with .24x + .14(10 - x) = ??? Do I need to include the 1.7 lbs of jasmine?
