Given
x^5*k=a .................(1)
x^2*k=b .................(2)
We need to find x^3.
Solution:
On inspection, we note that (1)/(2) gives x^3 on the left hand side, but the division is valid on conditions that x ≠ 0 and k ≠ 0.
So we conclude:
(1) / (2)
=>
=>
on condition that 
and

the answer to your question is 7
Ur not dumb!!! i graphed the line for u here. i suggest watching some khan academy videos for extra practice!
For the graphing if for example it says (3,-9) then you start at the very middle called the origin. Then go to the right 3.(this is called the x-axis) then go down 9 (this is the y axis) stop there and put you point. I hope this kinda helps explain this to you better :/
