Answer:
greatest common factor 12 and 26 is 2
Step-by-step explanation:
Let H represent hardcover
let P represent paperback
H + P = 20
H = P + 10
sub in H into the first eq’n
(P + 10) + P = 20
2P + 10 = 20
2P = 10
P = 5
sub P into eq’n 2
H + (5) = 20
H = 15
therefore there are 5 paperback books and 15 hardcover
