Explicación paso a paso:
2x-10=3x-30
2x-30x=10-30
-28x= -20
x= -28/-20
x= 1,4
[tex]x = 20[/tex]
[tex]2x - 10 = 3( x - 10)[/tex]
[tex]2x - 10 = 3x - 3 \times 10[/tex]
[tex]2x - 10 = 3x - 30[/tex]
[tex]2x - 10 + 10 = 3x - 30 + 10[/tex]
[tex]2x = 3x - 20[/tex]
[tex]2x - 3x = 3x - 20 - 3x[/tex]
[tex] - x = - 20[/tex]
[tex] \frac{ - x}{ - 1} = \frac{ - 20}{ - 1} [/tex]
