Question

Which of the following equations could you solve by first adding six and then dividing by negative three? 3x - 6 = -9 6 - 3x = -9 -3x - 6 = -9 + 6 = -9

Answer 1

Answer: $-3x-6=-9$

Step-by-step explanation:

The proccedure shown in the problem is applied to solve for x and calculate its value.

One of the equations shown in the problem is:

$-3x-6=-9$

To solve for x you must_

- Add 6 to both sides of the equations:

$-3x-6+6=-9+6$

$-3x=-3$

- Then you must divide by -3:

$\frac{-3x}{-3}=\frac{-3}{-3} \\x=1$

Then the answer is: $-3x-6=-9$
