I assume you're trying to find x?
anonymous
  • anonymous
yes
hlambach
  • hlambach
Okay. So start with the 2, you need to get it to the other side.

first subtract x to do inverse

not x imeant 2

now u have 1/2x=8 what do u have to do to make 1/2x to 1x
anonymous
  • anonymous
idk
anonymous
  • anonymous
well 2 1/2 make a whole right?
hlambach

1/2x + 2 = 10 -2 -2 What do you get?
anonymous
  • anonymous
where did you get the other 2
anonymous
  • anonymous
so multiply by 2 to 8
anonymous
  • anonymous
to get x=?
anonymous
  • anonymous
i got 16 but it was wrong
hlambach
  • hlambach
The opposite of 1/2 is 2, which is why you need to multiply 8 by 2.
anonymous
  • anonymous
and where did you get the other 2??
anonymous
  • anonymous
the other 2 is to show inverse to both sides
anonymous
  • anonymous
but the 1/2 is not division its a fraction
anonymous
  • anonymous
we didnt divide
anonymous
  • anonymous
flip 1/2 to 2/1
anonymous
  • anonymous
2/1=2
hlambach
  • hlambach
You're trying to get 1/2 to the other side. So we're doing the opposite, just like we did with the +2 part in the equation. Instead of ADDING 2, we SUBTRACTED 2. Now to get x by itself, you need to multiply 1/2 by it's opposite. We are multiplying because fractions are really just division problems. So we multiply each side by 2. Got it?

  • anonymous
but this one isnt division
hlambach
  • hlambach
Like I said, fractions are just division problems. What you're doing to the 1 is DIVIDING it by 2.
hlambach
  • hlambach
1 divided by 2 = 1/2
hlambach
  • hlambach
Okay, let's try it a "different" way. You are multiplying x by 1/2, right? So do the opposite, DIVIDE both sides by 1/2.

16
anonymous
  • anonymous
but i tried that and it was wrong
hlambach
  • hlambach
It's right.
hlambach
  • hlambach
Plug in 16 for x and you'll see it's right. 1/2(16) + 2 = 10
hlambach
  • hlambach
1/2 * 16 = 8 8 + 2 = 10
anonymous
  • anonymous
but its said it was -16 after i got it wrong
hlambach
  • hlambach
Unless the original equation is -1/2x +2 = 10 You are right.
anonymous
  • anonymous
ok
