Answer:The first one is 2.333333333

Step-by-step explanation:Simplifying

5(2 + -1j) + (2j + -3) = 0

(2 * 5 + -1j * 5) + (2j + -3) = 0

(10 + -5j) + (2j + -3) = 0

Reorder the terms:

10 + -5j + (-3 + 2j) = 0

Remove parenthesis around (-3 + 2j)

10 + -5j + -3 + 2j = 0

Reorder the terms:

10 + -3 + -5j + 2j = 0

Combine like terms: 10 + -3 = 7

7 + -5j + 2j = 0

Combine like terms: -5j + 2j = -3j

7 + -3j = 0

Solving

7 + -3j = 0

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + -3j = 0 + -7

Combine like terms: 7 + -7 = 0

0 + -3j = 0 + -7

-3j = 0 + -7

Combine like terms: 0 + -7 = -7

-3j = -7

Divide each side by '-3'.

j = 2.333333333

Simplifying

j = 2.333333333
