Question

Encontrar tres soluciones de cada ecuación

1. x + y = -3
2. 3 x - y = 7
3. x = -1/2
4. 3 x + 2 y = 6
5. 5 x + 4 y = 20
6. 2 x + y = 7

Answer 1

 {x,y} = {-4,-1}  System of Linear Equations entered :  [1] -3x - 8y = 20   [2] -5x + y = 19 Graphic Representation of the Equations : -8y - 3x = 20 y - 5x = 19
