Answer:
2.09
Explanation:
log(small 9)5=7-3x
log5
/ =7-3x
log9
(Divide both logs separately to get their decimal number.)
0.698970004/0954242509=0.73248676
0.73248676-7 (Because with the regular numbers you flip signs, apparently.)
so that equals = -6.26751324
-6.26751324 / -3 (From the -3x)
and that equals =2.08917108
which corr. with 2.09.
