Please help with this math problem?

Mr. Wilson invested money in two accounts. His total investment was $30,000. If one account pays 6% in interest and the other pays 8% in interest, how much does he have in each account if he earned a total of $1,920 in interest in 1 year?

He invested $ in the 6% account and $ in the 8% account.

Let x be the amount put into the 6% account
Let 30000-x be the amount put into the 8% account

0.06x + 0.08(30000-x) = 1920
0.06x + 2400 - 0.08x = 1920
-0.02x = -480
x = 480/0.02
x = 480 x 50
x = 24,000

Answer:
$24,000 in the 6% account
$6,000 in the 8% account
