    Hello again!
    I have been stuck on a mesh current question for an hour, and repeated it more than 5 times but couldn't figure out why my results are wrong...

    I need to find I_1 and I_2 is this question.

    Here are my mesh equations:
    -10 + 2(I1-I2) + 4j(I1-I2) + 3jI2=0
    3I2 + 9jI2 + 4j(I2-I1) + 2(I2-I1) + 3j(I1-I2) - 3j(I2) = 0

    They lead to:
    I1(2+4j) + I2(-2-j) = 0
    I1(-j-2) + I2(7j+5) = 0

    which give an answer that is different from the book's answer.
    Can you help me figure out what's wrong? :)

    Peace.
