Answer:

(1) a+-+8+=+5%2A%28b+-+8%29

(1) a+-+8+=+5b+-+40

(1) 5b+-+a+=+32

and

(2) a+-+5+=+3%2A%28b+-+5%29

(2) a+-+5+=+3b+-+15

(2) 3b+-+a+=+10

Subtract (2) from (1)

(3) 2b+=+22

(3) b+=+11

Substitute this back in (1) or (2)

(1) 5%2A11+-+a+=+32

(1) a+=+55+-+32

(1) a+=+23

Carole is 23 and Carl is 11
