Answer 4

and @masri101 no i haven't

Answer 5

x=7

Answer 6

3x−5=9

Create equivalent expressions in the equation that all have equal bases.

3x−5=32

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

(x−5)=2

Since −5 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 5 to both sides.

More Detail
x=5+2

Add 2 to 5 to get 7.

x=7

Answer 7

sorry

Answer 8

i got 7

Answer 9

Great to see you!

This problem becomes much easier when we recognize that 9 is a power of the base 3: 9 = 3^2.

Then, you can rewrite the original equation as
\[3^{x-5}=3^{2}\]

Answer 10

since the base (3) is the same on both sides of this equation, the exponents are equal. Thus, x-5=2. What's x?
