Learn how to solve logarithmic equations problems step by step online. Solve the logarithmic equation log(2,1-1*x)=-2. Rewrite the number -2 as a logarithm of base 2. For two logarithms of the same base to be equal, their arguments must be equal. In other words, if \log(a)=\log(b) then a must equal b. We need to isolate the dependent variable x, we can do that by subtracting 1 from both sides of the equation. Divide both sides of the equation by -1.
