Question

If [5 2y] - 2[2x-1 2]=[3 8] , find x and y

Answer 1

Answer:

Assuming these are matrices,

[5 2y] - 2[2x-1 2] = [3 8]

[5 2y] - [4x-2 4] = [3 8]

[(7+4x) (2y-4)] = [3 8]

Now we get,

7+4x = 3

x=-1

and,

2y - 4 = 8

y=6

Answer 2

Answer:

x=8 and y=-1

Step-by-step explanation:

rey question correct gaa pettu

(5-2y)-2(2x-12) =(3,8)

5-2y=3 , -2(2x-12)=8

y= -1 , x=4
