Let smaller and larger numbers be S and L, respectively

Since one number is 4 less than 5 times the other, then we can say that:
L = 5S - 4 ----- eq (i)

Since the sum of the two numbers is 68, then we can say that: L + S = 68 ----- eq (ii)

5S - 4 + S = 68 ------ Substituting 5S - 4 for L in eq (ii)

5S + S = 68 + 4

6S = 72

S, or smaller number = 72%2F6, or highlight_green%2812%29


L = 5(12) - 4 ----- Substituting 12 for S in eq (i)

L = 60 - 4

Larger number, or highlight_green%28L+=+56%29

You can do the check!!
