Question

(Elimination using multiplication) 2x+y=0 5x+3y=2
Show all work step by step

Answer 1

1. Set Up:
 -3(2x + y = 0)
   -6x -3y =-3
    5x+3y = 2 <2nd equation
     -1x=-1 <divide by -1
 > x = 1
2. Plug In:
 2(1) + y = 0
     2 + y = 0
    -2         -2
  > y = -2
3. Check Answer:
 2(1) + (-2) =0
> 2 - 2 =0
