Question

4+log subscript 9(3x-7)=6

Answer 1

subtract 4 from both sides

\[\log _{9} (3x - 7) = 2\]

raise each side as a power of 9

and remember

\[9^{\log _{9}(3x - 7)} = 3x - 7\]

then

\[(3x - 7) = 9^2\]

3x - 7 = 81

3x = 88

I'll let you finish the problem

Answer 2

did u get 261?

Answer 3

where did you get 261 from?

Answer 4

i subed the 88 in for x and did that whole problem over is that wrong??

Answer 5

the problem is asking you to find an x, so that when you put it into the original equation, it will be true.

campbell figured out the
3x= 88
that means 3 times x (the number we are looking for) is 88
or x+x+x= 88
x is definitely less than 88 (it takes 3 of them to get 88)
you solve for x by dividing both sides by 3

Answer 6

wow i feel slow -_-

Answer 7

If this were easy it would not be math

Answer 8

so with 3x=88
what is x?

Answer 9

Do you know how to find x if
3x=88
?

Answer 10

no :/
