Question

Heather has some comic books Susan has 12 more comic books then Heather Mary has one third as many comic books as Susan find all the ways that the number of comic books Heather has can be represented

Answer 1

Let S be the number of susan books and let m be the number of mary's book and Let h be the number of Heather's book

If Susan has 12 more comic books than Herther, then, this implies that

h = s - 12

If Mary has one third as many comic book as Susan. This implies;

m = 1/3 s

s= 3m

substituting s= 3m in the first equation

h = 3m - 12

Therefore, the ways to find the number of comic books Heather has can be represented​ as:

h = s - 12

h = 3m - 12
