-6bx=7b_{2}
Add 7b_{2} to both sides. Anything plus zero gives itself.
\left(-6b\right)x=7b_{2}
The equation is in standard form.
\frac{\left(-6b\right)x}{-6b}=\frac{7b_{2}}{-6b}
Divide both sides by -6b.
x=\frac{7b_{2}}{-6b}
Dividing by -6b undoes the multiplication by -6b.
x=-\frac{7b_{2}}{6b}
Divide 7b_{2} by -6b.
