64^x=16^x-1====> Make the bases the same
4^3(x)=4^2(x-1)=> Solve for x by bringing down the exponent without the base.
3(x)=2(x-1)=====> Distribute
3x=2x-2======> Now solve for x
3x = 2x-2
-2x -2x
x=-2
Therefore x is negative two

Answer:

Step-by-step explanation:

When converting mixed numbers (such as the one above), to improper fractions, we must first multiply the whole number by the denominator:

Then, add the numerator the the product:

Now, put the sum over the denominator to get your solution:

-
To check your work, you can convert the improper fraction to a mixed number to make sure you will end up with
.
Divide
into
:
with a remainder of 
Put the remainder over the denominator:

Therefore, our solution is correct!
The simplified answer is 0.25-3x
