Answer:
[tex]x=6[/tex]
Step-by-step explanation:
So we have the equation:
[tex]3(x+1)=9+2x[/tex]
Distribute the left side:
[tex]3x+3=9+2x[/tex]
Subtract 2x from both sides. The right side cancels:
[tex](3x+3)-2x=(9+2x)-2x\\x+3=9[/tex]
Subtract 3 from both sides:
[tex](x+3)-3=(9)-3\\x=6[/tex]
So, x is 6.
