Question 207859This question is from textbook intermediate algegra
: Find the solution to each systm by the addition (elimination) method.
26. 4s - 5t = 18
6s +10t = -8
I thought i understood this last semester think i an just confusing myself. my answers were t = -2 and s = 7 to me it just doesn't seem right. This question is from textbook intermediate algegra

26. 4s - 5t = 18 x2 --> 8s - 10t = 36
6s + 10t = -8
8s - 10t = 36
------------- Add
14s = 28
s = 2
---------
t = -2
