Question

Given the equation 2x +4 = 4x -2, select the reasoning that correctly solves for x.
A.add 2, subtract 2x, then divide by 2
B.add 2, subtract 4x, then divide by -2
C.subtract 4, subtract 2x, then divide by -2
D.subtract 4, subtracts 4x, then divide by 2.

Answer 1

A.

Cause we're just solving for x, to isolate it.
So
2x + 4 = 4x -2
You first subtract add 2 to both sides (whatever you do to one side you ave to do to another)
2x + 4 + 2 = 4x - 2 + 2
2x + 4 + 2 = 4x
Then you subtract 2x from both sides so all your x coefficients are on the same side.
2x + 4 + 2 - 2x = 4x - 2x
4 + 2 = 4x - 2x
Now, you combine your like terms.
6 = 2x
Divide by -2 to completely solve for x.
x = 3

Answer 2

Ok thank you

Answer 3

You would divide by 2, not -2

Answer 4

That's what I meant sorry. Lol no prob x

Answer 5

Ok so I divide by 2 and should get -3

Answer 6

No,

6 = 2x
/2 /2

x = 3

Answer 7

If it were negative it would've been x = -3

Answer 8

I agree that the answer is A

Answer 9

Yesh the answer is a, though there was a typo :3

Answer 10

Oh okay thanks

Answer 11

-(3x-2)=-4 (x+1) -4 do I distribute?

Answer 12

Post it on a different question, its starts to lag after a while
