Question

Help me solve: Assign real numbers to x and y
a) x + (y - 1)i = -1 + 3i

Answer 1

The real and imaginary parts are independent of one another. All you need to do is take the real part of each side of the equation, solve for x. And then take the imaginary part of each side of the equation, and solve for y.

Answer 2

y-1= 3 x=-1

Answer 3

I am only confused which parts exactly do I start with. The real parts are the ones without the i right?

Answer 4

ya right...

Answer 5

Ive been told how to solve these kinds of equations is ab + cd and ac - bd ?

Answer 6

there shud i in it

Answer 7

Yeah I know.
do I solve it like this:
x*-1 + (y-1)i*3i ?

how do I find the values of x and y?

Answer 8

its just a two variable equation

Answer 9

Oh my goodness, cant believe I forgot my own algebra equation solving skills :P at least with more than one variable. .-.

Answer 10

the real numbers for x and y is x= -1 and y=3 right? I solved it to be -2 + 5i I think its wrong...
