Answer:
Step-by-step explanation:
We know that for two similar matrices 
and 
exists an invertible matrix 
for which
![[tex]B = P^{-1} AP](https://tex.z-dn.net/?f=%5Btex%5DB%20%3D%20P%5E%7B-1%7D%20AP)

Answer:
Roy is 10 years old at present and Joan is 5 years old at present
Step-by-step explanation:
Let
x----> Roy's age
y----> Joan's age
we know that
x=2y ----> equation A
(x+3)+(y+3)=21 ----> equation B
substitute equation A in equation B
(2y+3)+(y+3)=21
solve for y
3y+6=21
3y=21-6
3y=15
y=5 years
Find the value of x
x=2y ----> x=2(5)=10 years
therefore
Roy is 10 years old at present
Joan is 5 years old at present
