Answer:
Option (a) is correct.
2.25 – 11j – 7.75 + 1.5j = 0.5j – 1 simplifies to j = -0.45
Step-by-step explanation:
Given : The linear equation 2.25 – 11j – 7.75 + 1.5j = 0.5j – 1.
We have to solve the given linear equation.
Consider the given linear equation 2.25 – 11j – 7.75 + 1.5j = 0.5j – 1.
Subtract 0.5j both side, we have,
2.25 – 11j – 7.75 + 1.5j - 0.5j = 0.5j – 1 - 0.5j
Simplify, we have,
2.25 – 11j – 7.75 + 1.5j - 0.5j = -1
Adding like terms, we have,
-5.5 -10j = -1
Adding 5.5 both side, we have,
-10j = -1 + 5.5
-10j = 4.5
Divide both side by -10, we have,
j = -0.45
Thus, 2.25 – 11j – 7.75 + 1.5j = 0.5j – 1 simplifies to j = -0.45
