x = [tex]\frac{15}{2}[/tex]

-3( - x - 2 ) 5x - 9 ( distribute parenthesis by multiply terms by - 3 )

3x+ 6 = 5x - 9 ( subtract 5x from both sides )

3x - 5x + 6 = - 9

- 2x + 6 = - 9 ( subtract 6 from both sides )

- 2x = - 15 ( divide both sides by - 2 )

x = [tex]\frac{- 15}{- 2}[/tex] = [tex]\frac{15}{2}[/tex]
