Explicación paso a paso:
[tex]9x-4 = 2x[/tex]
[tex]9x -2x = 4[/tex]
[tex]7x = 4[/tex]
[tex]x = \frac{4}{7}[/tex]
[tex]Comprobacion:[/tex]
[tex]9x -4 = 2x[/tex]
Sustuimos el valor de " x " por " [tex]\frac{4}{7} ".[/tex]
[tex]9(\frac{4}{7} )-4 = 2(\frac{4}{7} )[/tex]
[tex]\frac{9*4}{7} -4 = \frac{2*4}{7}[/tex]
[tex]\frac{36}{7} -\frac{8}{7} = 4[/tex]
[tex]\frac{36-8}{7} = 4[/tex]
[tex]\frac{28}{7} = 4[/tex]
[tex]4 = 4[/tex]
[tex]4-4 = 0[/tex]
[tex]0 = 0[/tex]
