x/(4+yi) +1/2i = 1
I will need another equation to solve the two unknowns but I can do some factirization as follows:
Multiplying up and down by (4-Yi) we obtain:
(X(4-Yi)/(16+Y) + (4-Yi)/(8i+2Yi)=1
X(4-Yi)(8i+2Y) + (4-Yi)(16+Y) = (16+Y)(8i+2Yi)
X(8i+2Y) + (16 + Y) = (4+Yi)(8i+2Yi)
Repit, I need another equation to continue
