x = amount invested at 11% profit
y = amount invested in stock
x + y = 14.000 (equation)
0.11x - 0.05y = 1.380
x = 14.000 - y
0.11(14.000 - y) - 0.05y = 1.380
1.540 - 0.11y - 0.05y = 1.380
0.16y = 160
y = 10.000
x = 14.000 - 10.000
x = 4.000
amount invested at 11% = $4,000
amount invested in stock = $10,000
