Engr. Ronald say: 12 = 1/2x
x = 24 answer//
-
MICHAEL K say: 1/2x = 12
(2/1)1/2x = (2/1)12
x = 24.
-
king say: 12*2x=1
24x=1
x=1/24

Victoria Briseno say: To find 'X', try isolating it on one side of the = sign. To do that, you have to separate it into: 12 = (1/2) times X for a better view. To get rid of the 1/2 on the side with X, divide the left and the right by 1/2 (since we are ISOLATING the X)
12/(1/2) = 24 and (1/2)X/(1/2) = X, so now we have X= 24

Fazaldin A say: 12 = 1/2x,
So,
x = 1 / 2*12 = 1/24. <----------------------------/

peevee say: Simplest way ; If half x is 12, full x has to be 24.
Mathematically:
1/2x =12 i.e., x * 1/2 = 12.
x = 12 x 2/1
12 x 2/1 =24.
-
lenpol7 say: 12 = (1/2)x
x = 12 X 2/1
x = 24
-
Michael say: 24

Jim Moor say: Your question would be interpreted, according to PEMDAS, as
12 = (1/2)(x)
Rule 1: what you do to one side of equal sign, you must do to both.
Multiply by 2 (both sides of course)
24 = x
then:
x=24
===
However, you might have meant
12 = 1/(2x)
multiply both sides by 2x
24x = 1
x = 1/24
===
So you see, standards and parentheses are very important.

Nedim say: Multiply the equation by 2.
-
Tutor say: 12/1 = 1/2x
You need to use cross multiply here.
12*(2x) = 1*1
24x=1
Divide both side by 24
24x/24 = 1/24
X=1/24
To check that your answer ia correct, you should put this value back into your original equation and make sure both side are equal.

Krishnamurthy say: x = 24
-
Zoella say: if 12=1/(2x) then multiplying both sides by 2x gives us 24x=1 so x=1/24
if 12=(1/2)x or 12=0.5x then we can multiply both sides by 2 and have x=24
