You need to undo that -27 so you can isolate s.
jimthompson5910 (jim_thompson5910):
So how do you undo that operation?
OpenStudy (anonymous):
S=-13 I don't really know how to explain how I got it... :(
jimthompson5910 (jim_thompson5910):
You undo it by adding 27 to both sides You want the left side to have -27+27 = 0 The 0 will go away (leaving just s behind)
jimthompson5910 (jim_thompson5910):
s-27=-40 s-27+27=-40+27 s + 0 = -13 s = -13
