5 ( x + 6 ) = 5 x + 30

12 x - 25 ¡Ý 3 x - 5 ( x + 6 )

12 x - 25 ¡Ý 3 x - ( 5 / x - 6 ) )

12 x - 25 3 x - ( 5 x + 30 )

12 x - 25 ¡Ý 3 x - 5 x - 30

12 x - 25 ¡Ý - 2 x - 30

Add 2 x to both dides

12 x - 25 + 2 x ¡Ý - 2 x + 2 x - 30

14 x - 25 ¡Ý - 30 Add 25 to both sides

14 x - 25 + 25 ¡Ý - 30 + 25

14 x ¡Ý - 5 Divide both sides by 14

x ¡Ý - 5 / 4
