Solución !

#1

[tex]2x - 5 = 5( x - 4)[/tex]

[tex]2x - 5 = 5x - 20[/tex]

[tex]2x - 5x = - 20 + 5[/tex]

[tex] - 3x = - 15[/tex]

[tex]x = \frac{ - 15}{ - 3} [/tex]

[tex]x = 5[/tex]

#2

[tex]x + 3(x - 2) = 2x - 4[/tex]

[tex]x + 3x - 6 = 2x - 4[/tex]

[tex]2x = 2[/tex]

[tex]x = 1[/tex]

#3

[tex]2x = 18[/tex]

[tex]x = 9[/tex]

#4

[tex]3x = 24[/tex]

[tex]x = 8[/tex]

#5

[tex]x - 12 = 58[/tex]

[tex]x = 70[/tex]

#6

[tex]x - 8 = 30[/tex]

[tex]x = 38[/tex]
