To solve the equation -15x = 120, divide both sides of the equation by -15:
-15x / -15 = 120 / -15
This simplifies to:
x = -8
Therefore, x = -8.
-15x / -15 = 120 / -15
This simplifies to:
x = -8
Therefore, x = -8.

Next, divide both sides of the equation by -3 to solve for x:
(-3x) / -3 = 12 / -3
This simplifies to:
x = -4
Therefore, x = -4.
-3x + 2 - 2 = 14 - 2
This simplifies to:
-3x = 12
Next, divide both sides of the equation by -3 to solve for x:
(-3x) / -3 = 12 / -3

To have an infinite amount of solutions, the equation must simplify to the form 0 = 0 after combining like terms.
Let's simplify the equation 2(5x + 6) + 2 = -6x + __x + __:
First, distribute 2 to the terms inside the parentheses:
10x + 12 + 2 = -6x + __x + __
Combine like terms on both sides:
10x + 14 = -6x + __x + __
Next, combine the x terms on the right side:
10x + 14 = (__ - 6)x + __
To achieve 0 = 0, the coefficient of the x terms on both sides must be equal. Therefore, the coefficient of x on the left side is 10, and the coefficient on the right side must also be 10 for an infinite number of solutions.
Therefore, the missing values are 10 and -4.
-6x + 10x = 10x - 6x = 4x
So, the complete equation becomes:
10x + 14 = 4x + 10x
10x + 14 = 14x
This equation has an infinite number of solutions.
