Solving for X: The Logarithmic Equations
I figured them out, thank you. log x - log (x+11) = -1 log (x / (x+11)) = -1 x/(x+11) = 10-1 x/(x+11) = 0.1 x=0.1(x+11) x=0.1x+1.1 x-0.1x=1.1 0.9x=1.1 x=1.222... log4x-log4(x+15) =-1 log4(x/(x+15) = -1 x/(x+15)= 4-1 x/(x+15) = 0.25 x=0.25(x+15) x=0.25x+3.75 x-0.25x=3.75 0.75x=3.75 x=5- Alykayy
