Question

What is the sum of the solutions of ?
2|x-1|-4=-2
A. 0
B. 1 1/2
C. 2
D. -2

Answer 1

2(x−1)−4=−2
I will try to solve your equation.
2x−6=−2(Simplify both sides of the equation)
2x−6+6=−2+6(Add 6 to both sides)
2x=4
(2x)
2
=
4
2
(Divide both sides by 2)
x=2

Answer 2

Is that one part completed? Like are we supposed to solve the opposite of that too o. o

Answer 3

No, the answer is C

Answer 4

Is that - 4 or negative4

Answer 5

Because I solved using - 4

Answer 6

Oooh... I suppose. Thank you and it's - 4

Answer 7

2|x-1|-4=-2
2|x-1| = -2 + 4
2|x-1| = 2
|x-1| = 2/2
|x-1| = 1

x - 1 = 1
x_1 = 2

or
x - 1 = -1
x_2 = 0

the sum of x's = 2 + 0 = 2

Answer 8

Ok, goody! :D

Answer 9

I already solved it

Answer 10

but you have one x, while we should we have 2 x's. but the last answer is correct :)
