Solved 14 Solve The Following Simultaneous Equations Log Chegg Solving exponential equations where a substitution is needed and exponential simultaneous equations. examples: 1. solve the equation. 2 x 2 1 x = 3. 2. solve the simultaneous equations. 3 x × 9 y = 1. 2 2x × 4 y = 1 8. 1. put the logs into the same base. log9 x = log3 x log3 9 = 12log3 x log 9 x = log 3 x log 3 9 = 1 2 log 3 x. and log(xy) = log x log y log ( x y) = log x log y. so log3 x log3 y = 5 log3 x ×log3 y = −6 log 3 x log 3 y = 5 log 3 x × log 3 y = − 6. now it might feel more natural to work with variables that don't have log functions.

Consider the simultaneous equations e2x ey = 800 3 ln x ln y = 5 (a) for each equation, express y in terms of x. (b) hence solve the simultaneous equations. we need to rewrite the expression as a single logarithm. in order to apply the rules for combining logarithms, each log must have no coeffi cient in front of it.
