First add these fractions,
When we find common denominator; we get 1+logx+10-2logx = 5+5logx-logx-logx2
if you solve this equation, you will end up logx2 - 5logx +6=0
lets say logx=y
we get y2-5y +6 = 0 you need to factor this polynomial
y2 gives us y*y
6 gives us -6*-1 or -2*-3 (I chose negative factors because I need to add the factors to get -5 which is in the middle)
-6+-1=-7
-2+-3=-5 (we have to choose these factors)
y2-5y +6 =(y-2)(y-3) = 0 in this case
y-2 = 0 and y=2......logx=2
y-3 = 0 and y=3......logx=3
