= - 2i + 9 - 3i - 6 + 10i
= 5i + 3
= 3 + 5i
Slope is 12/6=2
y+6=2(x+4)
y=2x-2
Answer:


Step-by-step explanation:
We have been given the equation:

And 
Second equation can be rewritten as:

We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:


Now substitute
in equation (1) we get:





Answer: 34
Step-by-step explanation: you would have to add 14 to the other side. In math you have to do the opposite to cancel out sides. So to cancel -14 you would have to add 14 to -14 (making it zero) and 20 (making it 34)
Im bad at explaining but I hope you now kindof get it
