add 12 to both sides: 2x=38+12
myininaya
  • myininaya
2x=50
anonymous
  • anonymous
then you divide
myininaya
  • myininaya
Now divide both sides by 2: x=50/2=25

Oh! Thankyou
myininaya
  • myininaya
That's all. You not confused about any of the steps?
anonymous
  • anonymous
Actually i am
myininaya
  • myininaya
Where do you get stuck?
anonymous
  • anonymous
The first
myininaya
  • myininaya
So you know subtraction can be turned into addition right?
myininaya
  • myininaya
3-5=3+(-5)
anonymous
  • anonymous
Mhm
anonymous
  • anonymous
yea
anonymous
  • anonymous
but isnt it distributive property
myininaya
  • myininaya
So we have 12+-(12-x)=38
myininaya
  • myininaya
that - in front of that paranthesis can be read at -1
myininaya
  • myininaya
so what is -1(12-x)?
anonymous
  • anonymous
Huh??!!! you totaly confused
myininaya
  • myininaya
the changing subtraction to addition?
anonymous
  • anonymous
because for example she said to do multiplication during distributive property 3(12+9)
myininaya
  • myininaya
Right
anonymous
  • anonymous
(3*12)+(3*9)
myininaya
  • myininaya
yes so what is -1(12-x)
anonymous
  • anonymous
(-1*12)-(-1*x)
myininaya
  • myininaya
yes which =-12+x
anonymous
  • anonymous
yeeees
myininaya
  • myininaya
now we have x+(-12+x)=38
anonymous
  • anonymous
why do you have to change the sub sign
myininaya
  • myininaya
since addition is commutative and associative we have x+x-12=38
anonymous
  • anonymous
cant you just put 12x?
myininaya
  • myininaya
?
myininaya
  • myininaya
x+x=2x
myininaya
  • myininaya
so we have 2x-12=38
anonymous
  • anonymous
then i know
myininaya
  • myininaya
+12 on both sides giving us 2x=50 then divide both sides by 2
anonymous
  • anonymous
from here
myininaya
  • myininaya
ok
anonymous
  • anonymous
ohhhhhh i get it!!
anonymous
  • anonymous
