x = number of comics Ross bought
A = 10*x = amount spent on buying those x number of comics at $10 each
B = 17*(x-1) = amount Ross gets from selling every comic book except one
B-A = 17*(x-1)-10x = 7x-17 = profit = 49
7x-17 = 49
7x = 49+17
7x = 66
x = 66/7
x = 9.42857 approximately
Because x isn't a whole number, I'm thinking that there's a typo in the problem somewhere. I would double check with your teacher.
You are changing the sign on one so to keep an equilibrium you change the other sign too
For example, the unknown side is x, the other two sides are 70^ and 10^.
Remember that the total of all the angles in a triangle is equal to 180^
S1) Add 70^ + 10^ = 80^
S2) 180 - 80 = 100^
ANSWER x = 100^
