Answer:

x = 2

Explanation:

Simplify both sides of the equation.


x(2)+4x-9=x+1\\2x+4x+-9=x+1\\(2x+4x)+(-9)=x+1 (combine like terms)


6x+-9=x+1\\6x-9=x+1\\

subtract x from both sides.


6x-9-x=x+1-x\\5x-9=1

add 9 to both sides.


5x-9+9=1+9\\5x=10

divide both sides by 5


(5x)/(5) =(10)/(5) \\x=2
