Question

1) In order for the addition method to eliminated x from the two equations in a system, what
must be true about the x-terms in the two equations?

Answer 1

Answer:

The coefficients of the x-terms have opposite values.

Step-by-step explanation:

The x terms are opposite values (the coefficients of the x-terms have opposite values( one negative or one positive so that when added the answer is zero

Example     y + 24x = 50

              + 2y - 24x  = 40    

                  3y           =  90
