Expert Answer:

By space equality space of space matrices comma
straight p plus straight q plus straight r equals 9
straight p plus straight q equals 5
therefore space 5 plus straight r equals 9
therefore space straight r equals 9 minus 5 equals 4
Now comma space straight q plus straight r equals 7
therefore space straight q plus 4 equals 7
therefore space straight q equals 7 minus 4 equals 3
And comma space straight p plus 3 plus 4 equals 9
therefore space straight p plus 7 equals 9
therefore space straight p equals 9 minus 7 equals 2
