Question

X+5 over 3 = x-3 over 4

Answer 1

i posted this in the other than, does it look like this?
\[\frac{ x + 5 }{ 3 } = \frac{ x - 3 }{ 4 }\]

Answer 2

what can we do with that?

Answer 3

Yes

Answer 4

find x?

Answer 5

Common denominator rite?

Answer 6

ahhhhhhh!!

Answer 7

hahahahaha julie u are truely smart :]

Answer 8

so the lcd is obviously 12 which gets us?

Answer 9

Im lost

Answer 10

ok so the Least common denominator of 3 and 4 is 12 so you have to multiply
\[\frac{ x + 5 }{ 3 } * \frac{ 4 }{ 4 }\]

Answer 11

20x over 12?

Answer 12

yah. that rite.

Answer 13

no \[\frac{ 4x + 20}{12}\]
but i see where you could have done the 20x

Answer 14

Ooo wats nxt?

Answer 15

i mean the solution
@gaara438125

Answer 16

so the other side then becomes\[\frac{ 3x - 9 }{ 12 }\]
because we do \[\frac{ x - 3 }{ 4 } * \frac{ 3 }{ 3 }\]
so it looks like
\[\frac{ 4x + 20 }{ 12 } = \frac{ 3x - 9 }{ 12 }\]

Answer 17

multiply both sides by 12 to get what?

Answer 18

Idk hw to do that

Answer 19

since both sides are being divided by 12 you can multiply BOTH sides to rid of the fraction leaving only \[4x + 20 = 3x - 9\]

Answer 20

Do i combine like terms

Answer 21
