Can someone lease help me with the steps. I know the solution but I would like to know how to get it. Here's what I have: (-b)+((a+b+c)/2), I know that this needs to be equal to ((b-a-c)/-2)

Question

well i dont know if you got the wrong answer but i got (a-b+c)/2

-b is the same as (-b)/1
multiply that by 2/2 and you get (-2b)/2
and then simply add ((-2b) +(a+b+c))/2
(a-b+c)/2

Right, I missed the fact that ((b-a-c)/-2 is the same as a-b+c/2. Thank you so much:)
