Answer:
x = 20/7
Step-by-step explanation:
5x = 12x - 20
5x - 12x = -20
-7x = -20
x = 20/7
[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]
