12 − 5x + 6x = 4 - Given
12 + x = 4 - Combine Like Terms
x= −8 - Subtraction Property of Equality
Hope this answers the question. Have a nice day.
        
             
        
        
        
Answer:
Step-by-step explanation:
8(1 + 2i) -  (7 - 3i) = 8*1 + 8*2i + 7*(-1) - 3i*(-1)
                           = 8 + 16i -7 + 3i
                           = 8 - 7 + 16i + 3i
                           = 1 + 19i
Daniel forgot to multiply 2i by 8
 
        
             
        
        
        
Answer:
a. Practically speaking, you compute the differential in much the same way you compute a derivative via implicit differentiation, but you omit the variable with respect to which you are differentiating.
Aside: Compare this to what happens when you differentiate both sides with respect to some other independent parameter, say :
b. This is just a matter of plugging
