The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Divide both parts of the equation by (3^(log(3)^7) - x)/x
We get the answer: x = -5 + 3^(log(3)^7)
3^log(3)^7-x = 5
Expand brackets in the left part
3^log3^7-x = 5
Divide both parts of the equation by (3^(log(3)^7) - x)/x
x = 5 / ((3^(log(3)^7) - x)/x)
We get the answer: x = -5 + 3^(log(3)^7)
