correct
There are some minor flaws in your presentation
x+y=6300(-11) should have been
-11(x+y)=6300(-11) to get
-11x -11y = -69300
0.11x+ 0.08y=597(100) should have said
100(0.11x+ 0.08y)=597(100) to get
11x + 8y = 59700
The way you have it, the left side is not equal to the right side
$6300 is invested, part of it at 11% and part of it at 8%. For a certain year, the total yield is $nbsp 597.00 . How much was invested at each rate?
x+y=6300(-11)
0.11x+ 0.08y=597(100)
............................
11x+8y=59700
-11x−11y=−69300
...........................
−3y=−9600
y=3200
........................
x+3200=6300
x=3100
