Question

4x - (2x + 3)(3x - 5) = 49 - (6x - 1)(x - 2) ecuación

Answer 1

Respuesta:

x=-4

Explicación:

$4x - (6 {x}^{2} - 10x + 9x - 15) = 49 - (6 {x}^{2} - 12x - x + 2) \\ 4x - 6 {x}^{2} + 10x - 9x + 15 = 49 - 6 {x}^{2} + 12x + x - 2 \\ 5x - 6 {x}^{2} + 15 = 47 - 6 {x}^{2} + 13x \\ 5x - 13x - 6 {x}^{2} + 6 {x}^{2 } = 47 - 15 \\ - 8x = 32 \\ 8x = - 32 \\ x = - \frac{32}{8} \\ x = - 4$
