Answer 2

Let's solve each equation step by step:

1. -7 - 4x = -10x - 6

To solve this equation, we will simplify the expression by combining like terms:

First, let's move the terms with x to one side of the equation. We can do this by adding 10x to both sides:

-7 - 4x + 10x = -10x + 10x - 6

Simplifying the equation gives:

-7 + 6x = -6

Next, let's isolate the variable x. We can do this by subtracting -7 from both sides:

-7 + 7 + 6x = -6 + 7

Simplifying further:

6x = 1

To find the value of x, divide both sides of the equation by 6:

(6x)/6 = 1/6

Simplifying gives:

x = 1/6

Therefore, the solution to the equation is x = 1/6.

2. 5x - 3 = 12

To solve this equation, we will isolate the variable x. First, let's add 3 to both sides of the equation:

5x - 3 + 3 = 12 + 3

Simplifying:

5x = 15

Next, divide both sides of the equation by 5:

(5x)/5 = 15/5

Simplifying gives:

x = 3

Therefore, the solution to the equation is x = 3.

3. -x + 9 = 16

To solve this equation, we will isolate the variable x. First, let's subtract 9 from both sides of the equation:

-x + 9 - 9 = 16 - 9

Simplifying:

-x = 7

Next, multiply both sides of the equation by -1 to solve for x:

(-1)(-x) = (-1)(7)

Simplifying gives:

x = -7

Therefore, the solution to the equation is x = -7.
