Best ResponseYou've already chosen the best response.1OK, let's think of it this way: divide both sides by \(\large {1 \over 2}\).

Best ResponseYou've already chosen the best response.1Remember this? 2 x 1 = 2 2 x 2 = 4 2 x 3 = 6 2 x 4 = 8 2 x 5 = 10 2 x 6 = 12

Best ResponseYou've already chosen the best response.1Basically, you just wanna get the \(\rm x\) alone.

Best ResponseYou've already chosen the best response.1Think of it this way: we must divide both sides by \(\Large {1 \over 2}\) which just means multiplying 2. Right?

Best ResponseYou've already chosen the best response.0ok..so WHAT IF 1/2x is equals to 3..and it will look like 3/2=30?

Best ResponseYou've already chosen the best response.0What do mean if (1/2)x = 3? You multiplied by 2 in order to isolate the x...to let it alone on one side. So: \[x = 15 \times 2\]

Best ResponseYou've already chosen the best response.0why do we multiply it with 2 then?

Best ResponseYou've already chosen the best response.1As said above, we divide by onehalf which is the same as multiplying 2.

Best ResponseYou've already chosen the best response.0To UNDO the (1/2)x we multiply by 2. We want to solve for x, find it's value. So we need it isolated on one side.

Best ResponseYou've already chosen the best response.0Once you multiply by 2, the (1/2) is gone.
