+4

14 - 3(x+9) = 5     distribute the 3 across the terms in the parentheses

 

14 - 3x - 27   =  5       

 

14 - 27  - 3x  =  5

 

-13   - 3x  =   5  add 13 to both sides

 

-3x  =  18       divide both sides by -3

 

x  =   -6

14-3(x+9)=5

 

Subtract 14 from both sides.

 

14-3(x+9)-14=5-14

 

Simplify

 

-3(x+9)=-9

 

Divide both sides by -3

 

 

Simplify

 

x+9-9=3-9

 

Subtract 9 from both sides

 

x+9-9=3-9

 

Simplify

 

x=-6
