One number is 1 less than a second number. Twice the second number is
20 less than 4 times the first. Find the two numbers.
-----
Equations:
o = s -1
2s = 4o - 20
--------
Substitute for "o" and solve for "s":
2s = 4(s-1) - 20
2s = 4s -24
2s = 24
second # = 12
------
Solve for "o":
o = s-1
o = 12-1
o = 11
