Answer 1

Explicación paso a paso:

$1) \\ 3 + x - 2 = 3 + 1 \\ 1 + x = 4 \\ x = 4 - 1 \\ x = 3$

$2 )\\ - 2 + 5 = 6 - x - 2 \\ 3 = 4 - x \\ x = 4 - 3 \\ x = 1$

$3) \\ 2x + 4 + 3x - 1 = 7x - 2 - x \\ 5x + 3 = 6x - 2 \\ 5x - 6x = - 2 - 3 \\ - 1x = - 5 \\ x = 5 \\ \\ 4) \\ 4x - 9 = 2x + 3 \\ 4x - 2x = 3 + 9 \\ 2x = 12 \\ x = 12 \div 2 \\ x = 6$

$5) \\ 3x - 15 = 2x + 4 \\ 3x - 2x = 4 + 15 \\ x = 19$

$6) \\ 2 - x = x - 8 \\ - x - x = - 8 - 2 \\ - 2x = - 10 \\ x = 10 \div 2 \\ x = 5$

$7) \\ 2x - 1 = 5x + 8 \\ 2x - 5x = 8 + 1 \\ - 3x = 9 \\ x = 9 \div ( - 3) \\ x = - 3$

$8) \\ 3 + 3x - 1 = x + 2 + 2x \\2 + 3x = 3 x + 2 \\ 3x - 3x = 2 - 2 \\ 0x = 0 \\ x = 0 \\ \\ 9) \\ 2(1 + 2x) = 10 \\ 2 + 4x = 10 \\ 4x = 10 - 2 \\ 4x = 8 \\ x = 8 \div 4 \\ x = 2$

$10) \\ 2(3x - 2) = 2 \\ 6x - 4 = 2 \\ 6x = 2 + 4 \\ 6x = 6 \\ x = 6 \div 6 \\ x = 1\\ \\ 11) \\ - 2(3x - 2) = - 2 \\ - 6x + 4 = - 2 \\ - 6x = - 2 - 4 \\ - 6x = - 6 \\ x = 6 \div 6 \\ x = 1$
