Answer:

Correct, if 1/2(8x +14) =39, then x = 8

Step-by-step explanation:

[tex]\frac{1}{2}(8x+14)=39[/tex]

Solving for x: Multiplying both sides of the equation by 2

[tex]2[\frac{1}{2}(8x+14)]=2(39)\\ 8x+14=78[/tex]

Subtracting 14 from both sides of the equation:

[tex]8x+14-14=78-14\\ 8x=64[/tex]

Dividing both sides of the equation by 8:

[tex]\frac{8x}{8}=\frac{64}{8}\\ x=8[/tex]
