Every time I come up with a different answer!?!? Can someone explain and show the work/ with answer? Thank you soo much! Been working on it for at least a half an hour!
Just needs some careful algebra...
-14.81 + 13.9v = 14.2v – 13.04
Add 13.04 to both sides:
-14.81 + 13.9v + 13.04 = 14.2v - 13.04 + 13.04
simplify a bit:
-1.77 + 13.9v = 14.2v
subtract 13.9v from both sides:
-1.77 + 13.9v - 13.9v = 14.2v - 13.9v
simplify again:
-1.77 = v(14.2 - 13.9)
-1.77 = 0.3v
divide both sides by 0.3:
v = -1.77/0.3
v = -5.9
Check back with the original equation:
-14.81 + 13.9(-5.9) = 14.2(-5.9) – 13.04
-14.81 - 82.01 = -83.78 - 13.04
-96.82 = -96.82
which is all fine.
Hope that made sense!

-96.82 = -96.82
