More easier method:
10=y+3x/x
10x=y+3x
7x=y
7=y/x
1/7=x/y.

[JeremyLionell]

I did it differently.
1) I multiplied both sides by x
10x= y+3x
2) Subtract both sides by 3x
7x= y
3) I then plugged in the value of y in the x/y question, so it becomes:
x/7x
4) There are two x'es so they cancel out. And we are left with 1/7

[rambrijmaurya]

Simple:
10 = y + 3x/x
10x = y + 3x
10x - 3x = y
7x = y
7=y/x
Therefore. ( reciprocal )
X/Y = 1/7

The guy had me laughing at "this problem looks impossible"

That's one of the easy ones

[globalolympiadsacademy]

Is not impossible as it is simply asking for ratio...if it had asked for individual values of x and y, it's not possible to find unique solutions.

As far this problem goes, why don't we simply cross multiply and get 10x = y + 3x and it will give is 7x = y leading to x/y = 1/7

[abdullahimohamedalasow]

Another different method:
10= (y+3x)/y.
Subtract both sides by 3, which gives you 7=y/X, then the reciprocal is X/y =1/7.

Could you please also do a YT channel of your shorts that isn't rushed so I can understand instead of having to watch it so many times to understand and can go back to certain time stamps as well when I don't understand something and link it to the short vids?

I just solved algebraically and got 7x = y plug it in, you get 1x/7x x cancels = 1/7

[MrPaulc]

I got there with a different method:
a) 1 = ((y+3x)/10x) meaning that y+3x has the same value as 10x. Therefore, y=7x giving (x)/(7x), hence 1/7

[thekingofbel]

I did it differently because of how the question worded it instantly knew A was wrong and just plugged in B and C (x for the numerator and y for the demoninator) and it came out as C being the correct answer.

[EpicGritJourney]

10=y+3x/x so what yu can do is multiply x by both sides then yu will get

10x=y+3x then take 3x to the other side

10x -3x =y

Then 7x =y so x/y =1/7 thanks to yu all

[eaglehaus]

10x = y + 3x
10x - 3x = y
7x = y
7 = y / x
1 / 7 = x / y

Math is only fun when you understand it 🥲

[crystalannison]

I just subtracted the 2 numbers from the beginning and then turned it into fraction form😅

[XBGamerX]

you can use trig for it but its too complex

[jediwarrior]

u can't just flip the numerator and the denominator. u have 7=y/x
u multiply 1/49 to 7 to make it 1/7 but u have to multiply even y/x with 1/49.
edit:what u are actually doing when u flip the numerator and the denominator is u are raising both the sides to the -1 power

[terranceparsons]

I just went with c). It's always c).

[lukabakhtadze]

10X=y+3X
7X=y
replace y with 7X X/7X
cancel out X an you get 1/7

[FoosterExtra]

Too easy, solve it before the tutor like me.
By writing as: 10x= y+3x=> 7x=y=> x/y=7 however, inverse is 1/7

This is like grade 6th or 7th maths 😂😂
