<h3>What is an 
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables. 
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let a represent the amount invested at interest of 10% and b represent the amount invested at 8%, hence:
a + b = 155000    (1)
Also:
0.1a + 0.08b = 14100    (2)
From both equations:
a = 85000, b = 70000
Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%

Answer:
x = ± 2i
Step-by-step explanation:
note that  = i
 = i
x² = - 12 ( take square root of both sides )
x = ±  = ±
 = ±  = ± 2i
 = ± 2i
