solve for x
log (42x-1) = log (32x+3)
log 4 (2x-1) = log3 ( 2x+3)
log4 / log3 (2x-1) = 2x+3
1.2619 (2x-1) = 2x+3 can you take it from here? the others are similar .....
...or you can just ignore the power and just do the exponent
for the first one:
subtract 2x from both sides and add 1 to both sides to get no solutions
