Here's about half of it...

x = Amount invested at 6%
y = Amount invested at 4%

Translate!!

"r Kyung had $6,000 to invest in two savings accounts"

x + y = $6000

"At the end of the year, Kyung had earned a total of $290 in interest "

x*0.06 + y*0.04 = 290

Do you REALLY want me to believe there was something in there that you couldn't do?

Make Definitions and Translate.  ALWAYS a great start to things.
