Question

Can someone walk me through this please?
(x+2)+(2x-1)=4x-7

Answer 1

I'm so sorry if I am keeping you waiting. I am trying to work this out to see if I wil get the answer right so I can correctly walk you through it. I haven't done math in a while. :P

Answer 2

Oh its ok! Thanks

Answer 3

Open the bracket first
x+2x=3x and 2-1=1, So we have\[3x+1=4x-7\]

Answer 4

i dont understand how you got that tbh...

Answer 5

Collecting like terms, we have\[4x-3x=7+1\]

Answer 6

What is tbh?

Answer 7

to be honest
sorry

Answer 8

ok so how do i find like terms...like i need baby steps on this

Answer 9

\[(x+2)+(2x-1)=4x-7\]
\[x+2+2x-1=4x-7\]
\[x+2x+2-1=4x-7\]

Answer 10

so you flipped x+2 and x+2x around? IM RETARDED IM SO SORRY RN!

Answer 11

Oh wait you need to find x, don't you? Okay. Well first we would have to simplify both sides of the equation. So let's start with (x + 2) + (2x + 1).

You would have to use what I believe is the distributive property to simplify this. You use imaginary 1s to take out the parenthesis.

1 * (x + 2) + 1 * (2x + 1)
x + 2 + 2x -1

Now that you have taken away the parenthesis, you combine like terms,

3x + 1

Now the equation is 3x + 1 = 4x - 7.

Now you will have to isolate the variable. You will do this by putting the variable on one side and the numbers on the other.

3x + 1 = 4x - 7

I can do this part with you since it's a little bit more difficult, would you know maybe how to isolate the variable?

Answer 12

Something like that, yeah

Answer 13

still a little confused..for real im sorry if i seem retarded but these are one of the things i dont get

Answer 14

Please, when you post something like "(x+2)+(2x-1)=4x-7," would you include the instructions? You yourself might understand the question better if you were clear about your goal here.

Removing parentheses, x + 2 + 2x - 1 = 4x - 7

combine like terms on the left side. Your result, please?

Answer 15

idk what like terms are..idk how to get them...

Answer 16

Given that A is between B and C. If AB = x+2, BC = 4x-7, and AC = 2x -1, find the x and AC. Could you explain because im having trouble? This is the original question but i plugged the numbers in and that part idk how to get

Answer 17

kewlgeek555 has already offered help with this: 3x + 1 = 4x - 7

x and 2x are "like" terms, as are 2 and -1.

What is the sum of x and 2x?
What is the sum of 2 and -1?
If you do this correctly you will get the same result as kewlgeek555 has already gotten.

Answer 18

@swimmerranae102000 , @Joshtray actually used the distributive property, just like I did, and took out the parenthesis with the imaginary 1s. When you have something like (x+2)+(2x-1), you should know that there are imaginary 1s that you can distribute (by multiplying) to take away the parenthesis.
