9x + -3 = 5x + -15
Reorder the terms:
-3 + 9x = 5x + -15
Reorder the terms:
-3 + 9x = -15 + 5x
Solving
-3 + 9x = -15 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
-3 + 9x + -5x = -15 + 5x + -5x
Combine like terms:
9x + -5x = 4x
-3 + 4x = -15 + 5x + -5x
Combine like terms:
5x + -5x = 0
-3 + 4x = -15 + 0
-3 + 4x = -15
Add '3' to each side of the equation.
-3 + 3 + 4x = -15 + 3
Combine like terms: -3 + 3 = 0
0 + 4x = -15 + 3
4x = -15 + 3
Combine like terms: -15 + 3 = -12
4x = -12
Divide each side by '4'.
x = -3

The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number. Hope it helps!

Answer:
D. Undefined
Step-by-step explanation:
4-4 = 0, 10-6 = 4
Change of x = 0
Change of y = 4
Since the change of x is 0 (a horizontal line), it is undefined.
