    Solve for ix in the following circuit using source transformation:


    So here's what I did:


    I'm confused how I find ix now, unless I did something wrong...? Maybe I'm supposed to convert the current source to voltage? Can someone help ASAP? Thanks. :)

    Firstly, you have calculated wrong the value of the resistor. When two resistor end up being parallelly connected, in order to find their equivalent you don't add them. The equivalent is R_{eq}=\frac{R_1\cdot R_2}{R_1 +R_2}.
    Addition only works for resistors connected in series.

    Also, when two current sources are connected in parallel, they can be replaced with a single current source with double the current rating.
