Multiply both sides by 2.

OK, let's think of it this way: divide both sides by \(\large {1 \over 2}\).

  • anonymous
and what do u mean multiply?
ParthKohli
  • ParthKohli
Multiplication... is... the... basic... thing... they... teach... you... in... multiplication... tables.

  • ParthKohli
Remember 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

Basically, you just wanna get the \(\rm x\) alone.

i'm sorry why do we multiply 2 to both sides is what i meant ;)
ParthKohli
  • ParthKohli
Think of it this way: we must divide both sides by \(\Large {1 \over 2}\) which just means multiplying 2. Right?
anonymous
  • anonymous
yes
anonymous
  • anonymous
we multiply x by 2?
ParthKohli
  • ParthKohli
Both sides.
anonymous
  • anonymous
can u demonstrate?
ParthKohli
  • ParthKohli
\[\rm {1 \over 2}x\cdot 2 = {15 \cdot 2} \]
anonymous
  • anonymous
then the answer will be?
ParthKohli
  • ParthKohli
\[15 \cdot 2\]
anonymous
  • anonymous
ok..so WHAT IF 1/2x is equals to 3..and it will look like 3/2=30?
anonymous
  • anonymous
What 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: \[x = 15 \times 2\]
anonymous
  • anonymous
why do we multiply it with 2 then?
ParthKohli
  • ParthKohli
As said above, we divide by one-half which is the same as multiplying 2.
anonymous
  • anonymous
To 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.
anonymous
  • anonymous
Once you multiply by 2, the (1/2) is gone.
