10) 3x + 1 = ( - 3)( - 7) ( ley se signos : ( - )( - ) = + 3x + 1 = 21 3x = 20 x = 20 / 311) x + 1 / 3 = x / 2 ( multiplicaos en aspa) 2x + 2 = 3x 2 = x12) 2x - 1 = 3x + 1 - 1 - 1 = 3x - 2x - 2 = x13) x + 1 / 2 = 2x + 1 / 3 ( multiplicamos en aspa) 3x + 3 = 4x + 2 3 - 2 = 4x - 3x 1 = x14) 3x + 5 / 4 = x + 1 / 3 ( multiplicamos en aspa) 9x + 15 = 4x + 4 5x = - 11 x = - 11 / 5.
