Answer: (4-4i)+(3-2i) = 7-6i
Step-by-step explanation:
To add or subtract two complex numbers, just add or subtract the corresponding real and imaginary parts. For instance, the sum of 4 -4i and 3 - 2i is 7 -6i. The numbers in standard form will be a + bi, where a is the real part and bi is the imaginary part.
Answer:
x=5/2
Step-by-step explanation:
1. 13=6x-2 (add 2 to each side)
2.15=6x (divide each side by 6)
3.15/6=x (simplify the fraction by dividing by 3)
4.5/2=x (answer)
