Give me 5 mins ill solve it :)

The area of a rectangle gets reduced by 9 square units, if its length is reduced by 5 units and breadth is increased by 3 units. If we increase the length by 3 units and the breadth by 2 units, the area increases by 67 square units. Find the dimensions of the rectangle
sol
Area of rectangle = l*b
In the first case..
The area of a rectangle gets reduced by 9 square units, if its length is reduced by 5 units and breadth is increased by 3 units
So length = x = x-5
breath = y = 3+y
Area =
(x-5)(3+y) = (xy)-9
xy+3x−5y−15 = xy−9
3x−5y−6=0
In the second case =
If we increase the length by 3 units and the breadth by 2 units, the area increases by 67 square units
Length = x + 3
Breadth = y+2
Area =
xy+67=(x+3)(y+2)
xy+67=xy+2x+3y+6
2x+3y−61=0
So we have 2 equations..
3x−5y−6=0
2x+3y−61=0
By substitution, we can solve it
3x−5y−6=0
x = 5y+6/3
Substitute value of x in the second equation
When we substitute we will have only 1 variable and hence you will be able to solve it :)
Then when you get the value of y....substitute in equation 1 to get x
Ans...x value is 17
y value is 9
THIS WAS HER ANSWER BUT IT WAS IN SUBSTITUTION METHOD

So... you've to use elimination method and solve it, Enjoy xD

Same!
edit: how many times do you know how to solve the problem? Heck, how many times to I know how to solve the problem?!

Don't understand what? The equation?

You sent me into a deep state of confusion with that math problem
OHHH MYYYY GODSSS ITS SO NEAATTTT AND THANK YOUU!! I have a meeting with my maths teacher at 7:30 and this saved my day!!

On a completely different note, I just realised that I've been on GR for about 5 hours today in total. this site is addictive!!!
Booklover wrote: "anyone in the same problem as me?"yup- but my mom started making me close it at 2 o'clock. I am currently sneaking on as she has gone for a walk.

you don't think i haven't done that *sobs*
BUT MOM!! I SUGGESTED THE CHALLENGE!! DO YOU HAVE ANY IDEA HOW IT FEELS WHEN I SUGGESTED THE CHALLENEGE AND YET I DONT PARTICIPATE?
Niharika- asdfghjkl!! aaahh, I can't imagine being without books for a month! when I was a kid my parents put me on a month bookish hiatus (apparently one Nancy Drew in two days wasn't good for 7 y/o me) I only lasted 2 weeks lol. also what's the TNTBR challenge? I keep on forgetting, lolBlobbie- you're kidding!
Aashi- ahaha, I wish I could deny, but #relatable! my GR screen is open on one tab and my zoom on other. I keep on refreshing the latter every 40 mins lol.
if my parents ever did that, i'd still find a way to read, cause there's way too much stuff my parents don't know
Wait, Niharika, you suggested the challenge??! you should def (re ask) ask your mom! I've found out that repeating 'please' at least 15 times for a stretch either a) makes my mom incredibly irritated that she doesn't allow me to do ____ or b) she says yes. let's hope that the latter happens with your mom! xD.
