Question 217826
If a, b are elements of the REAL numbers and a+b=0, then a= -b.
I am having trouble with the steps, I kinda of know what types of axioms I need to use. Inverse and DEF. of Subtraction are some of those.


Step 1.  Given {{{a+b=0}}}


Step 2.  Add -b to both sides of the equation:  {{{a+b-b=0-b}}}


Step 3.  Simplify to both sides of the equation to get:   {{{a=-b}}}  ANSWER


I hope the above steps were helpful.
