HELP PLEASE!!<br> 100 POINTS!!
Brut [27]

Answer:

x=2

Step-by-step explanation:

We are given:

\displaystyle \frac{w^{-x+4}}{w^{-3}}=w^{2x+1}

First, by the quotient property:

w^{(-x+4)-(-3)}=w^{2x+1}

Since they both have the same base, their exponents must be equivalent:

(-x+4)-(-3)=2x+1

Solve for x. Simplify:

-x+7=2x+1

Therefore:

3x=6\Rightarrow x=2
