Question

15-28i=3l+(4m)i solve

Answer 1

What are you solving for? Is i a variable or complex number?

Answer 2

yes it is for complex number

Answer 3

and that is a 3l like the letter L or is it a 31?

Answer 4

it is the letter L, im trying to fine L & M

Answer 5

For L
3L=15-28i-(4M)i
3L=15-4i(7+M)
\[L=5-\frac{4i}{3}(7+M)\]

For M
(4M)i=15-28i-3L
(4M)i=3(5-L)-28i
(4M)=3(5-L)/i-28
(4M)=3(L-5)i-28
\[M=\frac{3(L-5)i}{4}-7\]

Answer 6

Is this what you mean? :)
