Which of the given values of x and y make the following pair of matrices equal `[3x+7 5y+1 2-3x],[0y-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`

Text Solution

Verified by Experts

The correct Answer is:
N/a
`[{:(3x+7,5),(y+1,2-3x):}],[{:(0,y-2),(8,4):}]`
`therefore 3x+7=0implies x=-(7)/(3)`
`5=y-2implies y=7`
`y+1=8implies y=7`
`2-3x=4implies x=(-2)/(3)`
Both values of x are not same .
therefore , it is not possible to find x and y .
