Answer:
- To solve the following equation we must first combine like terms
- Recognize the easiest way to manipulate the equation
- Lastly rearrange to isolate for x: usually done with division
2x+3x-11x-6=0
Combine like x variables
-6x-6=0
Add 6 to the right side
-6x = 6
Divide by -6
x=-1

The difference between the numbers ABCD and DCBB is 10000
<h3>How to determine the difference</h3>
From the information given, we have that:
- ABCD and DCBB is a multiple of 10.
- The digits A,B,C and D are consecutive integers
- The number ABCD is a multiple of 3
We can say that:
B + D = 10
A = 3
B = 4
C = 5
D = 6
Now,
ABCD = 3456
DCBB = 6544
Difference between the numbers ABCD and DCBB = 3456 + 6544 = 10, 000
Thus, the difference between the numbers ABCD and DCBB is 10000

By using Euler's notation, we will see that:
z^7 = 78,125*e^(-i*4.48)
<h3>
How to get z^7?</h3>
We know that:
z = 4 - 3i
Remember that for a complex number:
w = a + bi
In Euler's notation, we can write this as:
w = √(a^2 + b^2)*e^(i*Atan(b/a))
Then, for z, we will get:
z = √(4^2 + (-3)^2)*e^(i*Atan(-3/4))
z = 5*e^(-i*0.64)
Now, if we apply an exponent of 7 to this number, we will get:
z^7 = ( 5*e^(-i*0.64))^7
z^7 = 5^7*e^(-i*7*0.64) = 78,125*e^(-i*4.48)
