Answer 17

yup!

Answer 18

10 * (2x-4)
20x - 40 = 2x

Answer 19

correct! good! now bring 2x to the left side so that all x terms are on one side..

Answer 20

x=4/19 should i explanin again

Answer 21

basically u are subtracting 2x on both sides

Answer 22

ok i was just about to ask if i had to minus oor divide

Answer 23

@annie12m ummmm are you paying atention to what im saying?????????.......... orrrr whaaaat

Answer 24

20x - 40 = 2x
-2 -2
18x -40 = x

Answer 25

if the terms are in addition/subtraction then u do only that.. ex:if u have 2x on one side it becomes -2x when it goes to the other side of the eq

Answer 26

sorry @123AB456C im just want to know if yourboth correct

Answer 27

where is the x part ?

Answer 28

i asked to subtract "2x" on both sides

20x - 40 = 2x
-2x -2x

Answer 30

ya i did i just didnt write it in but thats what i did

Answer 31

then how come u have x on the right side?

Answer 32

oh did i have to get rid of it? i thought i just minused 2 of the things from it and there was still 18 x's left on that side

Answer 33

20x - 40 = 2x
-2x -2x
---------------
18x-40 = 0

Answer 34

ok?

Answer 35

ohhhh i see i see

Answer 36

now add 40 on both sides

Answer 37

18x = 40

Answer 38

good ! now div by 18 on both sides to have only x on left side..

Answer 39

2.2222

Answer 40

yes but mostly they will expect in fraction..so reduce 40/18

Answer 41

cancel with 2

Answer 42

what do u get?

Answer 43

no there is only 1 answer box

Answer 44

oh..cant u write fraction in that..?

Answer 45

no if there wwas a box on top of that one box then yes but not this time

Answer 46

ok ok then 2.22 is correct! !anyway 40/18 = 20/9 (cancel with 2 )
so 20/9 or 2.22 is the correct answer!
