Original equation: %28-3j%2F4%29+%2B+2=-1
Step 1: Subtract '2' to both sides to get %28-3j%2F4%29 by itself
%28-3j%2F4%29+%2B+2=-1
%28-3j%2F4%29=-3
Step 2: To get rid of the fraction and to get 'j' by itself, we must multiply the fraction by its reciprocal.. this will cancel the fraction out. We must do this to both sides of the equation.
%28-3j%2F4%29%28-4%2F3%29=-3%28-4%2F3%29
Step 3: Simplify
%28-3j%2F4%29%28-4%2F3%29=-3%28-4%2F3%29
j=%2812%2F3%29
Step 4: Continue simplifying
j=%2812%2F3%29
j=4
The answer is j=4
