x = 2
Step-by-step explanation:
4 x + (negative 4) = negative 2 x + 8
4x + (-4) = - 2x + 8
4x - 4 = - 2x + 8
4x + 2x = 8 + 4
6x = 12

Answer:
22 - 34i
Step-by-step explanation:
note that i² = - 1
Given
(5 - 4i)(6 - 2i) ← expand factors using FOIL
= 30 - 10i - 24i + 8i²
= 30 - 10i - 24i - 8 ← collect like terms
22 - 34i
