Question

Solve the following absolute value equation.

z? = 7
=
-
X = 15
X = - [?]
Notice that the negative sign is already entered!
Enter

Answer 1

Hey there!

`|\displaystyle(x-1)/(2) |=7`

Let's say that x-1 is negative:

`\displaystyle(-x+1)/(2) =7`

The first step is to multiply both sides by 2:

`\text{-x+1=14}`

Now, move 1 to the right, using the opposite operation:

`\text{-x=14-1}`

`\text{-x=13}`

Divide both sides by -1:

`\text{x=-13}`

• Note: Since the negative sign is already entered, all you need to enter is 13.

I hope you find my answer helpful.

Good luck!

Have a great day!
