5 Consider this system of equations:
5x + y = -2
2x - 2y=4

x  = 0

  y  = -2

Step-by-step explanation:

The given system of equation are:

   5x + y = -2

   2x - 2y = 4  

The problem here is to find x and y from the expression

   5x + y = -2     i

   2x - 2y = 4     ii

 So;

i x 2 :  10x + 2y  = -4      iii

ii x 5 :  10x - 10y  = 20     iv

   iii - iv;   12y  = -24

                  y  = -2

    Now find x;

             5x + y  = -2

             5x  - 2  = -2

                  x  = 0

the answer is b
