Aw_{8}=169x^{16}
Variable w_{8} cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by w_{8}.
\frac{Aw_{8}}{A}=\frac{169x^{16}}{A}
Divide both sides by A.
w_{8}=\frac{169x^{16}}{A}
Dividing by A undoes the multiplication by A.
w_{8}=\frac{169x^{16}}{A}\text{, }w_{8}\neq 0
Variable w_{8} cannot be equal to 0.
