Question

Si A= (2 , 3) , B=(3 , -2) y C= (4 , -1) , resolver la ecuacion : 2A – 3 [ 1/2 ( B – 3C) + 3/4 X ] = 1/4 X + 3C

Answer 1

2A-(3/2)(B-3C)-(9/4)x=(1/4)x+3C

2A-(3/2)B+(9/2)C-3C=(1/4)x+(9/4)x

2A-(3/2)B+(3/2)C=(5/2)x

(4,6)+(-9/2,3)+(6.-3/2)=(5/2 a, 5/2 b)

(11/2 , 15/2) =(5/2 a , 5/2 b)

a= 11/5        b=3
