Answer 1

Respuesta:

$6x - 1 = 2 - 9 \\ 6x - 1 = - 7 \\ 6x = - 7 + 1 \\ 6x = - 6 \\ x = - 6 \div 6 \\ x = - 1 \\ comprobación \\6 \times ( - 1) - 1 = 2 - 9 \\ - 6 - 1 = - 7 \\ - 7 = - 7 \\ \\ 1 - x = 9 + x \\ - x - x = 9 - 1 \\ - 2x = 8 \\ x = 8 \div ( - 2) \\ x = - 4 \\ comprobacion \\ 1 - ( - 4) = 9 + ( - 4) \\ 1 + 4 = 9 - 4 \\ 5 = 5$

Explicación paso a paso:

$2 - 5x = 2x - 12 \\ - 5x - 2x = - 12 - 2 \\ - 7x = - 14 \\ x = - 14 \div ( - 7) \\ x = 2 \\comprobación \\ 2 - (5 \times 2) =( 2 \times 2) - 12 \\ 2 - 10 = 4 - 12 \\ - 8 = - 8 \\ \\ 3x - 1 = 8 - 6x \\ 3x + 6x = 8 + 1 \\ 9x = 9 \\ x = 9 \div 9 \\ x = 1 \\ comprobacion \\ (3 \times 1) - 1 = 8 - (6 \times 1) \\ 3 - 1 = 8 - 6 \\ 2 = 2$
