Question 119053


{{{s=a+b+c}}} Start with the given equation




{{{0=a+b+c-s}}}Subtract s from both sides



{{{-c=a+b-s}}} Subtract c from both sides



{{{c=(a+b-s)/(-1)}}} Divide both sides by -1 to isolate c




{{{c=-a-b+s}}} Divide



{{{c=s-a-b}}} Rearrange the terms



--------------------------------------------------------------

Answer:

So our answer is {{{c=s-a-b}}}
