Question

Find the value of x + y if 3x - ix + 2y + yi = 5 + 4i, where i = √-1

Answer 1

@apoorvk Please help?

Answer 2

equate the real values and imaginary values of both sides

Answer 3

Okay, just compare the real an imaginary parts:

3x + 2 y = 5 .....{real}

and

(-x + y)i = 4i
or, -x + y = 4

Answer 4

solve these two linear equations, and find out 'x' and 'y'!

Answer 5

Oh ok! I think I go tit.
3x + 2y = 5
2x - 2y = -8
x = -3/5
y = 3.4
3.4 - 0.6 = 2.8?

Answer 6

Yup, right-O!!!

Answer 7

Thanks! I just didn't know that we could do that.
