Question

5(×+2)=3(×+1)+9 ¿cual es el resultado?​

Answer 1

$5(x + 2) = 3(x + 1) + 9$

$5x + 10 = 3x + 3 + 9$

$5x + 10 = 3x + 12$

$5x = 3x + 12 - 10$

$5x = 3x + 2$

$5x - 3x = 2$

$2x = 2$

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

$x = 1$

Verificamos

$5((1) + 2) = 3( (1) + 1) + 9$

$5(3) = 3(2) + 9$

$15 = 6 + 9$

$15 = 15$

15 = 15 Verdadero
