The solution

You have entered [src]
log(1/3)*(5*x2 + x - 15) = log(1/3)*(x - 10)
$$\left(\left(x + 5 x_{2}\right) - 15\right) \log{\left(\frac{1}{3} \right)} = \left(x - 10\right) \log{\left(\frac{1}{3} \right)}$$
Detail solution
Given the equation:
log(1/3)*(5*x2+x-15) = log(1/3)*(x-10)

Expand expressions:
15*log(3) - x*log(3) - 5*x2*log(3) = log(1/3)*(x-10)

log(1/3)*(5*x2+x-15) = 10*log(3) - x*log(3)

Reducing, you get:
5*log(3) - 5*x2*log(3) = 0

Expand brackets in the left part
5*log3 - 5*x2*log3 = 0
