Quick Math question solution
 

ok this is a simple math problem problem that im having trouble with plz help.

ok

3/4 y - 1/4 y= 5


ive tried 2 different solutions and still cant find the answer. cuss:

you lost me... what kind of math is this? Just algebra solving for y? What are the underscores for? And the numbers on the top and bottom?
EDIT: nvm you editted it

y=10

3/4y - 1/4y = 1/2y
then
1/2y=5
so 5/.5 = 10

is 1/4 and 3/4 a fraction, or is it 4 divided by 3 etcs

aight, thanks man.

These are some of the basic problems that we'll be tested on in the actual GED test. Simple enuff eh? I suggest you all stay in school

that shouldn't really matter. Fraction bars mean division.

it equals 2.5

3\4y - 1\4y=5
subtract them
1\2y=5
divide 1\2y by 1\2 and do the same to 5
thus
y=2.5

oOo:


y=10

close, but 5 divided by 1/2 = 10 not 2.5. You are mulitpying when you should be dividing

happy: biggrin:

i wish they taught that to us in 5th grade. the_finger:

I Agree the answer is 10. Both sides of the equation bust be multiplied by 2 to isolate the y. Multiplying the left side of the equation leaves you with y, and multiplying the right side of the equation leaves you with 10. Thus y=10.

just make all the denominators the same and its easy oOo:

( 3y - 1y = 20)
(2y = 20)
(y=10)

wtf didnt see that other y. oOo: yep its 10.
