3 2/3

−3 2/3

Answer 1

To find the value of x, we can start by isolating x on one side of the equation.

−3x + 9 = −19

First, let's get rid of the 9 on the left side of the equation by subtracting 9 from both sides:

−3x = −19 - 9
−3x = −28

Next, we can isolate x by dividing both sides of the equation by -3:

x = (-28)/(-3)
x = 28/3

So, the value of x is 28/3, which can be written as 9 1/3 or 9.33 rounded to two decimal places.
Therefore, the correct answer is −3 2/3.

Answer 3

To solve for x in the equation 5x - 5 = 50, we can follow these steps:

Step 1: Add 5 to both sides of the equation to isolate the term with x:
5x - 5 + 5 = 50 + 5
5x = 55

Step 2: Divide both sides of the equation by 5 to solve for x:
5x / 5 = 55 / 5
x = 11

So, the value of x in the equation 5x - 5 = 50 is 11.
