Answer: [tex]x=4[/tex]
Step-by-step explanation:
You need to solve for the variable x to find its value:
Add like terms:
[tex]-23=3x+9-11x\\-23=-8x+9[/tex]
Apply the Subtraction property of equality, subtract 9 from both sides of the equation:
[tex]-23-(9)=-8x+9-(9)\\\\-32=-8x[/tex]
Now, applying the Division property of equality, you can divide both sides of the equation by -8. Then you get:
[tex]\frac{-32}{-8}=\frac{-8x}{-8}\\\\x=4[/tex]
