2-4iyb=5+6i
Multiply -1 and 4i to get -4i.
-4iyb=5+6i-2
Subtract 2 from both sides.
-4iyb=3+6i
Subtract 2 from 5+6i to get 3+6i.
\left(-4iy\right)b=3+6i
The equation is in standard form.
\frac{\left(-4iy\right)b}{-4iy}=\frac{3+6i}{-4iy}
Divide both sides by -4iy.
b=\frac{3+6i}{-4iy}
Dividing by -4iy undoes the multiplication by -4iy.
b=\frac{-\frac{3}{2}+\frac{3}{4}i}{y}
Divide 3+6i by -4iy.
2-4iyb=5+6i
Multiply -1 and 4i to get -4i.
-4iyb=5+6i-2
Subtract 2 from both sides.
-4iyb=3+6i
Subtract 2 from 5+6i to get 3+6i.
\left(-4ib\right)y=3+6i
The equation is in standard form.
\frac{\left(-4ib\right)y}{-4ib}=\frac{3+6i}{-4ib}
Divide both sides by -4ib.
y=\frac{3+6i}{-4ib}
Dividing by -4ib undoes the multiplication by -4ib.
y=\frac{-\frac{3}{2}+\frac{3}{4}i}{b}
Divide 3+6i by -4ib.
