4x-3+7i=4+2y
Subtract 1 from 5 to get 4.
4x+7i=4+2y+3
Add 3 to both sides.
4x+7i=7+2y
Add 4 and 3 to get 7.
4x=7+2y-7i
Subtract 7i from both sides.
4x=2y+\left(7-7i\right)
The equation is in standard form.
\frac{4x}{4}=\frac{2y+\left(7-7i\right)}{4}
Divide both sides by 4.
x=\frac{2y+\left(7-7i\right)}{4}
Dividing by 4 undoes the multiplication by 4.
x=\frac{y}{2}+\left(\frac{7}{4}-\frac{7}{4}i\right)
Divide 7-7i+2y by 4.
4x-3+7i=4+2y
Subtract 1 from 5 to get 4.
4+2y=4x-3+7i
Swap sides so that all variable terms are on the left hand side.
2y=4x-3+7i-4
Subtract 4 from both sides.
2y=4x-7+7i
Do the additions in -3+7i-4.
2y=4x+\left(-7+7i\right)
The equation is in standard form.
\frac{2y}{2}=\frac{4x+\left(-7+7i\right)}{2}
Divide both sides by 2.
y=\frac{4x+\left(-7+7i\right)}{2}
Dividing by 2 undoes the multiplication by 2.
y=2x+\left(-\frac{7}{2}+\frac{7}{2}i\right)
Divide 4x+\left(-7+7i\right) by 2.
