    I assume you're trying to find x?

    Okay. So start with the 2, you need to get it to the other side.

    1/2x + 2 = 10 -2 -2 What do you get?

    The opposite of 1/2 is 2, which is why you need to multiply 8 by 2.

    the other 2 is to show inverse to both sides

    but the 1/2 is not division its a fraction

    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?

    Like I said, fractions are just division problems. What you're doing to the 1 is DIVIDING it by 2.

    1 divided by 2 = 1/2

    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.

    Plug in 16 for x and you'll see it's right. 1/2(16) + 2 = 10

    1/2 * 16 = 8 8 + 2 = 10

    Unless the original equation is -1/2x +2 = 10 You are right.
