Question

$3.(3 - \times ) + 9 = 2.( \times - 4) + 6$
​

Answer 1

¡Hola!

$3(3 - x) + 9 = 2(x - 4) + 6 \\ \\ 9 - 3 x+ 9 = 2x - 8 + 6 \\ \\ - 3 - 2x = - 8 + 6 - 9 - 9 \\ \\ - 5x = 6 - 26 \\ \\ x = \frac{ - 20}{ - 5} \\ \\ \boxed{x = 4}$

Vamos a comprobar...

$3( 3 - x) + 9 = 2(x - 4) + 6 \\ \\ 3(3 - 4) + 9 = 2(4 - 4) + 6 \\ \\ 3( - 1) + 9 = 2(0) + 6 \\ \\ - 3 + 9 = 0 + 6 \\ \\ 6 = 6$

Espero que sirva y saludos.

Answer 2

Respuesta:

x = 4

Explicación paso a paso:

$3.(3 - x ) + 9 = 2.( x - 4) + 6 \\ \\ 9 - 3x + 9 = 2x - 8 + 6 \\ \\ 18 - 3x = 2x - 2 \\ \\ 18 + 2 = 3x + 2x \\ \\ 5x = 20 \\ \\ x = \frac{20}{5} \\ \\ x = 4$
