Answer:

My answer is 8.428571429 ~ 8.43.

Step-by-step explanation:

First you can find log 5 which is 0.698970004 ~0.7. then you can use it to multiply the numbers in the bracket which will be 0.7x(x-7)=1...which will be 0.7x-4.9=1...then you will collect like terms which will be 0.7x=1+4.9 then it will be 5.9÷0.7 which will be equal to my answer above..Thank you for the question
