Answer 1

Hola

En el problema

9+2x-1=6x

[tex]9 + 2x - 1 = 6x \\ 8 + 2x = 6x[/tex]

[tex]8 + 2x = 6x \\ 2x + 8 = 6x \\ 2x + 8 - 8 = 6x - 8 \\ \: \:2x = 6x - 8[/tex]

[tex]2x - 6x - 8 \\ 2x - 6x = 6x - 8 - 6x \\ \: \: - 4x = - 8 \: \: \: \: \: \: \: [/tex]

[tex] - 4x \div - 4 = \frac{ - 8}{ - 4} = 2[/tex]

[tex] \bf \pink{ x = 2}[/tex]

Answer 2

Respuesta:

[tex]\large\boxed{\boxed{\bold{x = 2}}}[/tex]

9 + 2x - 1 = 6x

2x - 6x = -9 + 1

-4x = -8

-4x(-1) = -8(-1)

4x = 8

x = 8/4

x = 2

Comprobamos:

9 + 2x - 1 = 6x

9 + 2(2) -1 = 6(2)
