Question

Exercicio 7:
(2x-3)(x+7)=11xt11​

Answer 1

Creo que es así:

$(2x - 3)(x + 7) = 11x + 11$

$2 {x}^{2} + 14x - 3x - 21 = 11x + 11$

$2 {x}^{2} + 14x - 3x - 11x = 11 + 21$

$2 {x}^{2} + 11x - 11x = 32$

$2 {x}^{2} = 32$

${x}^{2} = \frac{32}{2}$

${x}^{2} = 16$

$x = \sqrt{16}$

$x = 4$

Espero haber ayudado.
