Answer:
Step-by-step explanation:
Let Age of Jim = x years
Age of George = (x/2) years
Age of Bill = x - 6
Their total age = 39 years
x + (x/2) + x - 6 = 39
[tex]x+\frac{x}{2}+x=39+6\\\\2x+\frac{x}{2}=45\\\\\frac{2x*2}{2}+\frac{x}{2}=45\\\\\frac{4x}{2}+\frac{x}{2}=45\\\\\frac{4x+x}{2}=45\\\\\frac{5x}{2}=45\\\\x=\frac{45*2}{5}\\\\x=9*2[/tex]
x = 18 years
Jim is 18 years old
