Question

the sum of a number and -14 is -32 find the number

Answer 1

-18

Answer 2

Your "sum of a number and -14" looks like
-14 + x

"is -32" looks like
= -32

Together, this is -14 + x = -32
Then you use algebra to solve for x.

Answer 12

does thaat look right?

Answer 13

Great :)

Answer 14

ok

Answer 15

is that -6 im confused

Answer 16

Yes. "6 less than a number" is the same as "a number subtract 6."

Answer 17

+4?

Answer 18

Let's test it. 4-6 = -2, so +4 won't work.
x - 6 = -10

We want x by itself, so we need to get rid of that -6. To get rid of a debt of 6, we add 6. Then, what we do to one side, we do to the other.
In summary, we add 6 to both sides.
x = -4

Answer 19

-4 I mean

Answer 20

thats why its good to always check ure answers

Answer 21

:)

Answer 22

twice the sum of a number and -2 is 16 find the number

Answer 23

Ideas?

Answer 24

2x+(-2)=-16

Answer 25

Very close. You're taking twice the sum. So you do the sum part, and then you double it.
2[x + (-2)] = 16

Answer 26

is that what the [ ] means?

Answer 27

Oh, it's just another way to write parentheses.
2(x + (-2)) = 16

Answer 28

so if I did not put parethsis I would have got it wrong?

Answer 29

Yes, you need parentheses, because the -2 needs to be multiplied by 2 as well.
