could someone please explain to me how to solve june 2010 Q 7

Using the log rules.......
2log3 (x-5) will become log3 (x-5)^2
Then by using the Subtraction rule for logs, it will become:

log3 (x-5)^2 over 2x-13 =1

This can then be simplified to:

(x-5)^2 over 2x-13= 3^1

Then by simplifying:

x^2 -10x+25=3(2x-13)

x^2 -10x+25= 6x-39

x^2 -16x +64

Hope this helps!!!
