−5
−4
2
8

Answer 1

what does x=

Answer 2

-5

Answer 3

Thank you again :P

Answer 4

ok wait yeah -5 i got mixed up sorry

Answer 5

It's okay! I fanned you <3

Answer 6

thanks how old r u

Answer 7

im 15

Answer 8

This is an expression, not an equation...

Answer 9

Code you arenʻt looking for x here, just the coefficient.

Answer 10

A coefficient is a number that is in front of a variable...in this case.... x :)

Answer 11

x is the variable, and -5 is in front of it. So that is your answer

Answer 12

yes i know i got mixed up

Answer 13

@Tal_Tal if we had 3 + x

What would the coefficient be?

Answer 14

3

Answer 15

you have to remember that in front of every variable, is an invisible 1. It multiplies itself by x.

The coefficient would be 1

Answer 16

Here is an easier one.

If we have....

2x + 3

What would the coefficient be?

Answer 17

2?

Answer 18

Yes! Correct :)

Answer 19

What about...

5 - x?

Answer 20

1?

Answer 21

Close! But itʻs a -1

Always remember to look at the signs. There is a negative sign that comes right before the x. This applies itself to the (1) that is multiplying by x.

Answer 22

One last one. What is the coefficient?

8 + 3 - 0.5x

Answer 23

Take your time on this, try read through what we just went over :)

Answer 24

0.5? or 1?

Answer 25

Mhm, itʻs not 1. Itʻs -0.5.

\[(-1)(0.5)(1)\]

The negative sign, or minus sign, is basically a -1 in this case...being multiplied by 0.5 and the 1 by the x. Once you finish multiplying, you get -0.5

Answer 26

Try read this over if you ever have any trouble

Answer 27

Iʻm sure youʻll get it :)

Answer 28

Thank you! I have a few more questions can you help me with them (I'll close this one)
