What about your text book?

Don't have one that covers logs with equations.

Give us an example.
Please don't make us guess as to what you mean.

something like this:
SOLVING LOGARITHMIC EQUATIONS ?

do you mean ...

1. using logarithms to solve exponential equations

or

2. solving logarithmic equations

in either case, they're both connected topics. here's a link starting from scratch ...

Logarithmic and exponential functions - Topics in precalculus

Solving simultaneous logarithmic equations.

It's the same principles as solving simultaneous equations using substitution. You can solve them by combining your log properties and your simultaneous equation knowledge.
