Respuesta :
In this type of situation the question gets divided into two parts;
6x=18 and 7iy=-21i
Now x=18/6 (Dividing both sides by 6) and y=-21i/7i (Dividing both sides by 7i)
x=3 and y=-3
Therefore option a is the answer.
6x=18 and 7iy=-21i
Now x=18/6 (Dividing both sides by 6) and y=-21i/7i (Dividing both sides by 7i)
x=3 and y=-3
Therefore option a is the answer.
