1. The problem statement, all variables and given/known data How can I solve these? Only using logarithms and(or) exponential(not natural logarithms, or e). 34x-1=7 35x/76x=4 3. The attempt at a solution I have tried turning the first one into log10. By doing Log34x-1=7 to Log104x-1/Log103=Log107, then somehow turning that into Log104x+Log10-1/Log103=Log107. But that doesn't seem right. It's where I'm stuck right now, can anyone help? Thank you.
