Question

Witch is NOT a method for solving systems of a linear equations

Answer 1

Answer:

  b. fundamental arithmetic

Step-by-step explanation:

While fundamental arithmetic is required when solving linear equations, the use of it is not a named method of solution.

"Substitution", "Elimination", and "Graphing" are named methods of solving linear equations. Sometimes the line can be blurred between substitution and elimination, but these methods generally involve distinct sets of steps (which include the use of fundamental arithmetic).
