Question

x + x = (4x+6 : X-3 =​

Answer 1

Respuesta:

$x + x = \frac{4 \times +6 }{x} - 3$

$x + x = \frac{4x + 6}{x} + - 3$

multiplicar ambos lados x y cancelar

$xx + xx = 4x + 6 + - 3x$

$2 {x}^{2} = x + 6$

$2 {x}^{2} - (x + 6) = x + 6 - (x + 6)$

$2 {x}^{2} - x - 6 = 0$

$(2x + 3)(x - 2) = 0$

$2x + 3 = 0or \: \: x \ = 2$

$x = \frac{ - 3}{2} \: orx = 2$

$x = \frac{ - 3}{2}$
