I invest $14,000, part is 15% and part is 2% if the total interest at the end of the year is $1060, how much did I invest at 15%

I think you mean that part (let'say x) earns 15% and the rest earns 2%

Solve thes two equations simultaneously:

x + y = 14,000

0.15 x + 0.02 y = 1060

0.15 x + 0.15 y = 2100

(I multiplied the first equation by 0.15)

0.13 x = 1040

I subtracted the second equation from the third)

Now finish it
