Question

Find the difference.
2x / 4xy - 6 / 2x

a. x - 3 / y
b. x - 6y / 2xy
c. x - 3 / 2xy - x
d. -5 / 2

Help please.

Answer 1

@elementwielder

Answer 2

\[\frac{ 2x }{ 4xy }- \frac{ 6 }{ 2x }\]

Answer 3

correct?

Answer 4

yes

Answer 5

simplify the individual terms first.
2x/(4xy) = 2/4 * x/x * 1/y
= ?

6/(2x) = 6/2 * 1/x
= ?

Answer 6

It is B correct?

Answer 7

simplify the equation so it is this\[\frac{ 1 }{ 2y }-\frac{ 3 }{ x }\]

Answer 8

B is not correct because where would you have drawn the extra "y" from?

Answer 9

so we automatically rule that out

Answer 10

B is right.

Answer 11

how so?

Answer 12

(9/3x) - (4/2x^2) =

(3/x) - (2/x^2) =

3x/x^2 - 2/x^2 =

(3x - 2)/x^2

Answer 13

wrong one xD

Answer 14

what lol? which one is wrong?

Answer 15

x/4xy - 6/2x
= x/2xy - (6/2x)(y/y)
= x/2xy - 6y/2xy
= (x-6y)/2xy

Answer 16

its B

Answer 17

im wondering why in your second step you multiplied y/y to 6/2x

Answer 18

to make the denominator common as xy
and yes, its B

Answer 19

as 2xy

Answer 20

oh true... i was thinking they were equal not as on one side of the equation

Answer 21

my bad
