What is the result of adding these two equations? 2x+3y=-5 5x-y=-12

Step-by-step explanation:

Step(i):-

Given equations are  2 x+3 y=-5  ...(i)

                                   5 x-y=-12 ...(ii)

Multiply equation (ii) by '3'

                                    2 x + 3 y  = -5  

                                   15 x - 3 y  = - 36

                                  17 x  = - 41

Step(ii):-

Substitute  in equation (i)

                             2 (+3 y=-5

                                 3 y = - 5 +

The solution of the two equations

 ( x, y ) =

answer: (1,3) and (-2,0) i think.
