the simpler operations first for this kind of problem...you're not an idiot...just need to practice doing more problems

Answer 19

for 3x + 2 = 11
undo the addition first, by subtracting from both sides

Answer 20

1 x = 11

Answer 37

3x + 2 = 11
subtract 2 from both sides

Answer 38

whoops
3-2 = 1 and 2- 2 = 0

Answer 39

don't subtract from 3x, because you already subtracted from the left side...subtract from the right side

Answer 40

y do u bother to help people on this site?

Answer 41

because I like to help ppl...IDK why...it's just fun for me

But, yeah, I try to help ppl until they understand on their own.
so, subtract 2 from both sides (the left and right side)

Answer 45

and you are left with 1x = 11

Answer 46

-2 -2
______________

Answer 48

solve that

Answer 49

whoops i subtracted 2 from 3 my bad

0 and 9

Answer 51

so now you have :
3x+0 = 9
or
3x=9

Answer 52

hah she left..... i must seriously be boring.... anywho back to aqw

Answer 53

oh she didnt leave

Answer 54

i think i get it now

Answer 55

unless there is another step

Answer 56

no...she didn't.
3x=9
undo the multiplication by dividing

Answer 57

3

Answer 58

oh yeah and im sry that I asked you what boobs felt like it was very inappropriate on my part....

Answer 59

IDK..I would think you were just curious

Answer 60

so, you divided by 3 and got x=3

try this one by yourself:
2x -1 = 7

Answer 61

hah no i have felt them before but i was just wondering how it felt from a girls perspecive

Answer 62

2 and 5 so 2x=5

Answer 63

I would normally just tell you, but IDK if this is a conservative site. I sometimes have weird/curous questions too and it's normal...

do you want to try the other problem?
2x-1 =7

Answer 64

no...look at the number that they are subtracting

Answer 65

they are subtracting -1 right

Answer 66

yeah...so you want to do the opposite...you want to add 1 to both sides

Answer 67

so -1 - -1 would be 0 and 7 - -1 would be 6

Answer 68

so 0x = 6 and now i divide

Answer 69

no...

Answer 70

leave the 2x alone when you subtract

Answer 71

x=0
