Question

if A+B=4j-i&A-B=i+3j find A&B​

Answer 1

Step-by-step explanation:

A+B=4J-I

A-B=3J+I

2A=7J

B=(4J-I)/7J

Answer 2

Step-by-step explanation:

A + B = 4j - i ----(1)

A - B = i + 3j ----(2)

Adding, equation (1) and (2)

2A = 7j

A = 3.5j

Now, Subtracting equation (1) and (2)

2B = j - 2i

2B = 2(j/2 - i)

B = j/2 - I
