Solving for x
Since x is on the right hand side of the equation switch the sides so it is on the left hand side of the equation.
2x+yi=-14-3i
Since yi does not contain the variable to solve for move it to the right-hand side of the equation by subtracting yi from both sides.
2x=-yi-14-3i
Divide each term in the equation by 2.
x = - yi / 2 - 7 - 3i / 2
Solving for y
Since y is on the right hand side of the equation switch the sides so it is on the left hand side of the equation.
2x+yi=-14-3i
Since 2x does not contain the variable to solve for move it to the right hand side of the equation by subtracting 2x from both sides.
yi=-2x-14-3i
Divide each term in the equation by i.
y=2xi+14i-3
x=-yi/2-7-3i/2
y=2xi+14i-3
