Question

What must be the relation between vectors A and B if the following condition is to be true: A-2B=-3(A+B) If Vector A=6x-2y, what is Vector B ?

Answer 1

-24x+8y

Step-by-step explanation:

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

A-2B = -3A-3B

+3A +2B. +3A +3B

4A = -B

B = -4A

Given A = 6x-2y

B = -4(6x-2y)

B =-24x + 8y

B = 8(-3x + y)
