Explicación paso a paso:
1. 19 - 3x = 10x - 7
19 + 7 = 10x + 3x
26 = 13x
2 = x
2. 7x - 10 = 5x + 22
7x - 5x = 22 + 10
2x = 32
x = 16
3. 5x - 3x = 27 - x
2x = 27 - x
2x + x = 27
3x = 27
x = 9
4. x/5 + 3 = 13
x + 15
--------------- = 13
5
x + 15 = 13 (5)
x + 15 = 65
x = 65 - 15
x = 50
5. 6( x - 2 ) + 2( x + 3 ) = 7( x + 10 )
6x - 12 + 2x + 6 = 7x + 70
6x + 2x - 12 + 6 = 7x + 70
8x - 6 = 7x + 70
8x - 7x = 70 + 6
x = 76
6.
x + 6
------------- = 2x - 6
5
x + 6 = 5 ( 2x - 6 )
x + 6 = 10x - 30
6 + 30 = 10x - x
36 = 9x
4 = x
7. 9x + 5( x - 10 ) = 12( x + 8 )
9x + 5x - 50 = 12x + 96
14x - 50 = 12x + 96
14x - 12x = 96 + 50
2x = 146
x = 73
8.
8x - 18
--------------- = 6 - 8x
5
8x - 18 = (5) ( 6 -8x )
8x - 18 = 30 - 40x
8x + 40x = 30 + 18
48x = 48
x = 1
