Question

Solve for x: -2(x + 3) = -2(x + 1) - 4.

A)2
B)3
C)All real numbers
D)No solutions

Answer 1

First you need to simplify! distribute the -2's and continue from there.

Answer 2

Multiply -2 by x and 3
Then multiply -2 by x and 1

Answer 3

@infiniterosha u there?

Answer 4

just like before, show us your work :)

Answer 5

wait, it's the same problem...?

Answer 6

Yeah its kinda the same thing. And sorry I was doing something

Answer 7

-2(3 + x) = -2(x + 1) + -4
(3 * -2 + x * -2) = -2(x + 1) + -4
(-6 + -2x) = -2(x + 1) + -4

Answer 8

-6 + -2x = -2(1 + x) + -4
-6 + -2x = (1 * -2 + x * -2) + -4
-6 + -2x = (-2 + -2x) + -4

Answer 9

looks good to tyhere

Answer 10

0=0

Answer 11

how did you get that?

Answer 12

I'm not saying it is wrong, but show me your work

Answer 13

because if you stop a little earlier, the answer becomes clear

Answer 14

Ok, because
-6 + -2x = -2 + -4 + -2x

-6 + -2x = -6 + -2x

-6 + 6 + -2x = -6 + 6 + -2x

Answer 15

ok, so stop at your second step there

Answer 16

-6 + 6 = 0
0 + -2x = -6 + 6 + -2x
-2x = -6 + 6 + -2x

Answer 17

so go back to the second step here \[-6 + -2x = -6 + -2x\]

Answer 18

pick an x, any x, will the equality hold?

Answer 19

simplifying equations

Answer 20

... uhm, random words, why are you saying that?

Answer 21

okay there were gonna combine like terms.

Answer 22

wait wait wait

Answer 23

I mean literally stop here \[-6 + -2x = -6 + -2x\]

Answer 24

okay.

Answer 25

ok, now, pick an x any x, will the equality hold? ie will this always be true for any value of x

Answer 26

3

Answer 27

that is just a number... I need words. I have no clue what you are saying if you do not explain yourself, if you are saying "let's try x=3," then go ahead, see if it works

Answer 28

I'm sorry someone was on my computer

Answer 29

ohk
