Asked by Pigga the black pig
which of the following systems of equations has the solution (-2, 1)
1. 2x - y = -5 and x + 2y = 10
2. y = -2x - 2 and 2x - 2y = 5
3. y = -3/2 x - 2 and 2x - y = -5
4. x - 4y = 8 and 3x + 10 = -2y
1. 2x - y = -5 and x + 2y = 10
2. y = -2x - 2 and 2x - 2y = 5
3. y = -3/2 x - 2 and 2x - y = -5
4. x - 4y = 8 and 3x + 10 = -2y
