1 answer

To find the value of x, we need to isolate the variable on one side of the equation.

First, we can start by subtracting 9 from both sides of the equation:

-3x + 9 - 9 = -19 - 9

This simplifies to:

-3x = -28

Next, we divide both sides of the equation by -3 to solve for x:

-3x / -3 = -28 / -3

This simplifies to:

x = 28 / 3

The value of x is 28/3, which can also be written as 9 1/3 in mixed number form.

Therefore, the correct answer is: 3 2/3
