<u>Substitute x and y values to get below system:</u>
<u>Divide the second equation by the first one and solve for b:</u>
- 80/10 = b³
- b³ = 8
- b = ∛8
- b = 2

Answer:
8-6i
Step-by-step explanation:
complex number in standard form will be in the form of a+bi
(-2 − 2i) + (10 − 4i) , open parenthesis
-2- 2i +10 -4i, group like terms
-2+10 -2i -4i, combine like terms
8 - 6i
