Answer:

x=5

Step-by-step explanation:

we have

[tex]3(x+2)+x=2x+16[/tex]

Solve for x

Distribute left side

[tex]3x+6+x=2x+16[/tex]

Combine like terms left side

[tex]4x+6=2x+16[/tex]

Group terms that contain the same variable

[tex]4x-2x=16-6\\2x=10\\x=5[/tex]

therefore

For x=5

The equation is true

Verify

substitute the value of x=5 in the original expression and evaluate

[tex]3(5+2)+5=2(5)+16[/tex]

[tex]3(7)+5=10+16[/tex]

[tex]26=26[/tex] ----> is true
