Find the ordered pair (s,t) that satisfies the system
s/5 + 5t = 3
3t + 6s = 9
+128475 Multiply the first equation through by - 30 and we have
- 150 t - 6s = -90 add this to the second equation and we get
-147t = -81
t = -81 / -147 = 27/49
To find s
3(27/49) + 6s = 9
81 / 49 + 6s = 9
6s = 9 - 81/49
6s = 360 /49
s = 360 / (49 * 6) = 60 / 49
(s , t) = ( 60 / 49 , 27 / 49)
