Question

(x + 2y)+ (2x-3y)i + 4i = 5

Answer 1

Answer:

$x = 1 \: \: \: \: \: y = 2.$

Step-by-step explanation:

$(x + 2y) + (2x - 3y)i + 4i = 5 \\ \\ x + 2y = 5 \: \: \: \: \: ...(i) \\ \\ 2x - 3y + 4 = 0 \\ \\ 2x - 3y = - 4 \: \: \: \: ...(ii) \\ \\ solving \: these \\ \\ 2x - 3y - 2x - 4y = - 4 - 10 \\ \\ - 7y = - 14 \\ \\ y = 2. \\ \\ x + 2(2) = 5 \\ \\ x = 1.$
