Dx=-40\times 8
Multiply both sides by 8.
Dx=-320
Multiply -40 and 8 to get -320.
xD=-320
The equation is in standard form.
\frac{xD}{x}=-\frac{320}{x}
Divide both sides by x.
D=-\frac{320}{x}
Dividing by x undoes the multiplication by x.
Dx=-40\times 8
Multiply both sides by 8.
Dx=-320
Multiply -40 and 8 to get -320.
\frac{Dx}{D}=-\frac{320}{D}
Divide both sides by D.
x=-\frac{320}{D}
Dividing by D undoes the multiplication by D.
