use systems of equations:
x+y=20000
.05x+.06y=1150
multiply the top equation by .05
.05x+.05y=1000
.05x+.06y=1150
subtract terms
-.01y=-150
divide each side by -.01
y=15000
so at the 6% rate he invested $15000
to find the 5% rate plug y into the very first equation
x+15000=20000
x=$5000

This is guess and check.
10000 each = 1100 interest
9000 and 11, 000 = 1110 interest
5000 and 15,000= 1150 interest
5,000 at 5%
15, 000 at 6% is the correct answer

Here’s the setup:
x + y = 20,000
.05x + .06y = 1,150
It sounds like you know how to go on from there.
