Given that:
James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3 .
To find:
The equation that can be used to solve for zach's age.
Solution:
Let the age of zach be Z.
Zach added 8 to his age = Z+8
And multiplied this sum by 3 = 3(Z+8)
James is 6 times older than his friend Zach = 6Z
Now,



Divide both sides by 3.

Therefore, the required equation is
is age of zach is 8 years.
3•2•7=42•2=84
12•10•7=840
84+840=924in^3
