in some country's Congress, the number of Representatives is 210 less than five times the number of senators. There are a total of 570 members. Find the number of Senators and the numbr of Representatives.
---------
Equations:
s + r = 570
r = 5s-210
-----
Substitute and solve for "s":
s + 5s-210 = 570
6s = 780
s = 130 (# of senators)
----
Solve for "r":
s + r = 570
130 + r = 570
r = 440 (# of representatives)
