3x + 2y = 19
x + y = 8
3 (x + y) = 3 (8)
3x + 3y = 24
3x + 2y = 19
-
3x + 3y = 24
--------------------
-y = -5
y= 5
x + y = 8
x + 5 = 8
x = 3
(3, 5)
Hi
arithmetic serie mean that to change from a rank to an other, you add "r"
So : if 6 is S1, and 2 is pace,
<u>then you need 8 hops to go from S1 to S9.</u>
<u> so you 'r going to add the reason 8 times. </u>
