Question

these is the part of matices​

Answer 1

Answer:

Step-by-step explanation:

X + Y = [5 2 ] (a)

1 3

X -Y =[1 -10] (b)

-5 7

From a and b we get

2X =[ 6 -8]

-4 10

Thus X = [3 -4]

-2 5

Let Y be [a b]

c d

Than from (a)

We get

[3 -4] + [a b] = [5 2]

-2 5 c d 1 3

[3+a -4+b] = [5 2]

-2+c 5+d 1 3

3 + a = 5 thus a = 2

-2 +c = 1 thus c =3

-4+b =2 thus b= 6

5+d =3 thus d= -2

Thus Y =[2 6]

3 -2
