17-x-3=16-8x
- Log (17-x-3) = Log (16-8x) ~ Take the base 10 log of both sides
- (-x-3)Log(17)=-8xLog(16) ~ Exponent rule for logs
- -xLog17-3Log17=-8xLog16 ~ Distribute
- -xLog17+8xLog16=3Log17 ~ Get x's to one side
- x(8Log16-Log17)=3Log17 ~ Factor out your x
- x=3Log17/(8Log16-Log17) ~ Divide by the non-x part
