2(x + 2) - 3(5 - x) = x + 5(x - 3)?

2(x + 2) - 3(5 - x) = x + 5(x - 3).

En resumen

2(x + 2) - 3(5 - x) = x + 5(x - 3) 2x + 4 - 15 + 3x = x + 5x - 15 2x + 3x - x + 5x = - 4 + 15 - 15 - 1x = - 4 X = - 4 \ - 1 X = 4.

2(x + 2) - 3(5 - x) = x + 5(x - 3)

2x + 4 - 15 + 3x = x + 5x - 15

2x + 3x - x + 5x = - 4 + 15 - 15 - 1x = - 4 X = - 4 \ - 1 X = 4.

ResolucióN

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

2(x + 2) - 3(5 - x) = x + 5(x - 3)

2x + 4 - 15 + 3x = x + 5x - 15 ⇒ Simplificamos 15

5x + 4 = x + 5x

4 = 6x - 5x

4 = x

Remplazo

2 ( 4 + 2 ) - 3 ( 5 - 4 ) = 4 + 5 ( 4 - 3 ) 12 - 3 = 9 ( 1 ) 9 = 9.
