Which of the given values of x and y make the following pair of matrices equal`[[3x+7, 5 ],[y+1, 2-3x]],[[0, y-2],[ 8, 4]]`
(a) `x=(-1)/3, y=7` (b) Not possible to find(c) `y=7, x=(-2)/3` (d) `x=(-1)/3, y=(-2)/3`

A

A: `x=(-1)/3, y=7`

B

B: Not possible to find

C

C : `y=7, x=(-2)/3`

D

D : `x=(-1)/3, y=(-2)/3`

Text Solution

Verified by Experts

The correct Answer is:
B
Option `B` is the correct answer
`[[3x+7, 5 ],[y+1, 2-3x]],[[0, y-2],[ 8, 4]]`
Equating the corresponding elements, we get
`3x+7=0=>x=-7/3`
