2×-4y=24
-6+4y=-24
What the answer??????

Sagot :

{ 2x - 4y = 24
{ - 6x + 4y = - 24    ⇒ ( - 4y + 4y = 0 )

2x - 6x = 24 - 24
- 4x = 0  .(-1)
  4x = - 0
    x = - 0 
           4
    x = 0

2x - 4y = 24
2.0 - 4y = 24
0 - 4y = 24
- 4y = 24 .(-1)
  4y = - 24
   y = - 24
           4
   y = - 6

S = { 0,-6}
