Question

Please show every single step.

x + 2 = 12
x - 9 = 26
5x = 40
x/4 = 3
2x - 4 = -2
2x + 7 = 19
(x/3) + 4 = 10
3x + 1 = 25
3x - 2 < 13
2x + 7 > 21

Answer 1

For the first one....

Answer 2

x + 2 = 12 for the first one what do you think.

Answer 3

x + 2 = 12

You need to undo the addition of 2 so that x is by itself. Understand? Subtract x by both sides.

x + 2 - 2 = 12 - 2

x = 12 - 2

What is 12 - 2?

Answer 4

You isolate need to get x by itself. if you see addition you do subtraction and whatever you do to one side you do to the other

Answer 9

Yup

Answer 10

the answer for the first one is 10

Answer 11

@nuccioreggie you know your answer is correct because 10+2 = 12

Answer 12

Do you know how to do number 2?

Answer 13

remember that the 9 is being subtracted, so do the opposite of subtraction to both sides. the opposite of subtraction is....?

Answer 14

x + 2 = 12

You need to undo the addition of 2 so that x is by itself. Understand? Subtract x by both sides.

So thats the answer for nummber 1

Answer 15

Yes

Answer 16

except the x should be 2 my mistake

Answer 17

Which x

Answer 18

@DIDITHEDAD

Answer 21

The "Subtract x by both sides" that needs to be "Subtract 2 by both sides"

Answer 22

x + 2 = 12

You need to undo the addition of 2 so that x is by itself. Understand? Subtract 2 by both sides.

x + 2 - 2 = 12 - 2

x = 12 - 2

x = 10



(Copy and paste that)

Answer 23

Wait to can you just re write number one out for me please

Answer 24

Lol nvm

Answer 25

x - 9 = 26

What do you think we do?

Answer 26

x + 2 = 12

You need to undo the addition of 2 so that x is by itself. Understand? Subtract 2 by both sides.

x + 2 - 2 = 12 - 2

x = 12 - 2

x = 10



So this the answer for number one?

Answer 27

yes

Answer 28

What do we do for number two?

x - 9 = 26

It is being subtracted, so we do the opposite....the opposite of subtraction is?

Answer 29

Ok so for number 2

Answer 30

Opposite of subtraction?

Answer 31

Addition

Answer 32

Yes...so

x - 9 = 26

Add 9 to both sides


x - 9 + 9 = 26 + 9

x = 26 + 9

what is 26 + 9?

Answer 33

35

Answer 34

Yup!

Answer 35

x - 9 = 26

Add 9 to both sides


x - 9 + 9 = 26 + 9

x = 26 + 9

what is 26 + 9= 35





So thats the answer for number 2?

Answer 36

5x = 40

5x is 5 times x. So this is multiplication...

Opposite of multiplication?

Answer 37

For number two,

x - 9 = 26

Add 9 to both sides

x - 9 + 9 = 26 + 9

x = 35

Answer 38

Ok 1sec im writing these down ok so i might take a little time to respond back but just dont leave the question im just writing these down ok

Answer 39

OKay

Answer 40

Ok im ready for 3 now

Answer 41

5x = 40

5x is 5 times x...

times is multiplication...

opposite of multiplication is what?

Answer 42

Division

And i didnt put that my computer does that sumtimes

Answer 43

Yup.

So divide 5 by both sides

5x = 40

5x/5 = 40/5

(The / means divided by)

x = 40/5

What is 40 divided by 5?

Answer 44

8

Answer 45

x = 8, CORRECT

Answer 46

5x = 40

Divide both sides by 5...

5x/5 = 40/5

x = 8

Answer 47
