-2dx=-70
Subtract 70 from both sides. Anything subtracted from zero gives its negation.
\left(-2x\right)d=-70
The equation is in standard form.
\frac{\left(-2x\right)d}{-2x}=-\frac{70}{-2x}
Divide both sides by -2x.
d=-\frac{70}{-2x}
Dividing by -2x undoes the multiplication by -2x.
d=\frac{35}{x}
Divide -70 by -2x.
-2dx=-70
Subtract 70 from both sides. Anything subtracted from zero gives its negation.
\left(-2d\right)x=-70
The equation is in standard form.
\frac{\left(-2d\right)x}{-2d}=-\frac{70}{-2d}
Divide both sides by -2d.
x=-\frac{70}{-2d}
Dividing by -2d undoes the multiplication by -2d.
x=\frac{35}{d}
Divide -70 by -2d.
