[tex]-13[/tex]
Explicación paso a paso:
[tex]x=5x-5x-13[/tex]
[tex]x -5x+5x = -13[/tex]
[tex]x+0 =-13[/tex]
[tex]x = -13[/tex]
[tex]Comprobacion:[/tex]
[tex]x = 5x-5x -13[/tex]
Sustituimos " x " por " -13 ".
[tex]-13 = 5(-13) -5 (-13) -13[/tex]
[tex]-13 = -65 + 65 -13[/tex]
[tex]-13 = 0 -13[/tex]
[tex]-13 = -13[/tex]
[tex]-13 + 13 = 0[/tex]
[tex]0 = 0[/tex]
