Question

if A=[:{(1,-2) (3,5) (5,7):}] and 2A-3B=[:{(4,1) (5,2) (-9,3):}],find B​

Answer 1

Answer:

Step-by-step explanation:

2*1 - 3x = 4 ==> x = -2/3 , 2*(-2) - 3y = 1 ==> y = -5/3

(-2/3,-5/3) .... first term of set B.

2*3 - 3x = 5 ==> x = 1/3 , 2*5 - 3y = 2 ==> y = 8/3

(1/3, 8/3) .... second term of set B.

2*5 - 3x = - 9 ==> x = 19/3 , 2*7 - 3y = 3 ==> y = 11/3

(19/3, 11/3) .... third term of set B.

So, B = {(-2/3,-5/3), (1/3,8/3), (19/3,11/3)}
