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]
