Explicación paso a paso:

1.-

$2x-7=-3\\\\2x = -3 +7\\\\2x = 4\\\\x = \frac{4}{2} \\\\x = 2$

2.-

$3x + 5 = -1\\\\3x = -1 -5\\\\3x = -6\\\\x = \frac{-6}{3} \\\\x = -2$

3.- 2x - 8 =10

$2x = 10 -8\\\\2x = 2\\\\x = \frac{2}{2} \\\\x = 1$

4.-

$5x - 7 + 2x = 4x + 5\\\\5x + 2x -4x = 5 + 7\\\\7x - 4x = 12\\\\3x = 12\\\\x = \frac{12}{3}\\\\x = 4$

5.-

$5x - 2x -4 = x + 7 -5\\\\5x - 2x -x = 7 -5 + 4\\\\5x - 3x = 11 - 5\\\\2x = 6\\\\x = \frac{6}{2} \\\\x = 3$

6.-

$x - (2x + 1) = 8 - (3x + 3)\\\\x - 2x - 1 = 8 - 3x - 3\\\\x - 2x + 3x = 8 - 3 + 1\\\\4x - 2x = 9 -3\\\\2x = 6\\\\x = \frac{6}{2} \\\\x = 3$

7.-

$2.(x-1) - 5 = 14 - x\\\\2x - 2 - 5 = 14 - x\\\\2x + x = 14 + 5 + 2\\\\3x = 21\\\\x = \frac{21}{3} \\\\x = 7$

8.-

$15x - 10 = 6x - (x-2) + (-x+3)\\\\15x - 10 = 6x - x + 2 - x + 3\\\\15x - 6x + x + x = 2 + 3 + 10\\\\11 x = 15\\\\x = \frac{15}{11}$

9.-

$x + 3(x - 1) = 6 - 4(2x + 3)\\\\x + 3x - 3 = 6 - 8x - 12\\\\x + 3x + 8x = 6 - 12 + 3\\\\12x = 9 - 12\\\\12x = -3\\\\x = \frac{-3}{12} \\\\x = \frac{-1}{4}$

10.-

$6 - 3.( x + 1) = -4x + 2.(1 - x)\\\\6 - 3x - 3 = -4x + 2 - 2x\\\\-3x + 4x + 2x = 2 + 3 - 6\\\\6x - 3x = 5 - 6\\\\3x = - 1\\\\x = \frac{-1}{3}$
