[tex] - 2 {x}^{2} + 10x - 6y = 12[/tex]
Explicación paso a paso:
[tex](7x - 3y + 9) + (2x - 3y - 15) = ( {x}^{2} + 4x) + ( {x}^{2} - 5x + 6) \\ 7x - 3y + 9 + 2x - 3y - 15 = {x}^{2} + 4x + {x}^{2} - 5x + 6 = \\ 9x - 6y - 6 = 2 {x}^{2} - x + 6 = \\ 9x - 6y - 2 {x}^{2} + x = 6 + 6 = \\ - 2 {x}^{2} + 10x - 6y = 12[/tex]
