[tex]x = \frac{20}{7} \\ \\ x = 2 \frac{6}{7} [/tex].

Step-by-step explanation:

[tex]5x = 12x - 20[/tex]

Collect like terms and simplify

[tex]5x - 12x = - 20 \\ - 7x = - 20[/tex]

Divide both sides of the equation by -7

[tex] \frac{ - 7x}{ - 7} = \frac{ - 20}{ - 7} [/tex]

Simplify

[tex]x = \frac{20}{7} \\ \\ x = 2 \frac{6}{7} [/tex]
