Question

What is the value of x in the following equation?

-3x - 2 = 2x + 8

A. -10
B. 02
C. 2.
D. 10

Answer 1

`x=-2`

Explanation:

To cancel out "- 2", we add 2 into both sides.

`-3x(-2+2)=2x+(8+2)`

`-3x=2x+10`

Now, we need to get rid of 2x so we can have one x.

Let's subtract 2x from both sides.

`(-3x-2x)=(2x-2x)+10`

`-5x=10`

To get x by itself, we will divide both sides by -5.

`(-5x)/(-5) =(10)/(-5)`

`x=-2`

The value of x in the given equation is -2. I do not see a -2 in the answer choices.

Answer 2

-2

Explanation:

-3x - 2x = 8 + 2

-5x = 10

x = -2
