Find the ordered pair (s,t) that satisfies the system
s/2 + 5t = 3 + 5t
3t - 6s = 9 + 3t
Find the ordered pair (s,t) that satisfies the system
s/2 + 5t = 3 + 5t
3t - 6s = 9 + 3t
s/2 + 5t = 3 + 5t
by observation s/2 = 3
s = 6
3t – 6s = 9 + 3t
by observation – 6s = 9
s = – 1.5
You can't have s equal to two different amounts
in the same system, so this system is invalid.
