In order to solve this equation, we will need to change the base of one half to two. Use a negative exponent to rewrite this term.

Rewrite the equation.

Since the bases are common, we can simply set the exponents equal to each other.

Solve for x.  Divide a negative one on both sides to eliminate the negatives.

The equation becomes:

Subtract  from both sides.

Divide both sides by negative four.

The answer is:  

When dealing with exponential equations, we want to make sure the bases are the same. This way we can set-up an equation with the exponents.

 With the same base, we can now write

 Subtract  on both sides.
