You can put this solution on YOUR website! Find real numbers x and y such that (2x+y)+(3-5x)i=1-7yi.
-------
Equate the Real Parts and the Imaginary parts to get 2 equations::
2x+y = 1
3-5x = -7y
-------------------
Rearrange::
y + 2x = 1
7y - 5x = -3
------------------------
Modify for elimination::
7y + 14x = 7
7y - 5x = -3
---------------------
Subtract and solve for "x"::
19x = 10
x = 10/19
-----------------
Solve for "y"::
y = -2x + 1
y = -(20/19) + (19/19)
y = -1/19
