   Solving Logarithmic Equations and Inequalities 7-4 Solve the equation log 2 (x + 17) = log 2 (3x + 23). Since the bases of the logarithms are equal, (x+ 17) must equal (3x+ 23). (x + 17) = (3x + 23) -6 = 2x x = -3 Property of Equality for Logarithmic Functions If b is a positive number other than 1, then log b x = log b y if and only if x= y ...
