Answer:

Expression = -23 + 26i

Step-by-step explanation:

Given the following data;

x = -5 + 6i

y = 3 - 2i

Expression = 4x - y

Substituting the values of "x" and "y" into the equation, we have

4(-5 + 6i) - (3 - 2i)

Expanding the bracket, we have;

Expression = -20 + 24i - 3 + 2i

Expression = -23 + 26i
