a + c = 433

a + b = 550

b + d = 781

c + d = 664

a + b + c + d = 1214

Spent 3 hours trying to figure this out today but to no avail. It’s just impossible.

Now aren’t you tempted to grab a piece of paper and a pen then try to work it out? 😉

**Note**: a, b, c & d can’t be 0.

Hi Jess! I think you will be “pek chek” when i tell you the answers.

a=0, b=550, c=433, d=231

Lol lol no no, I tried this method. But those will only be the answers if we assume a = 0. But if we don’t assume a = 0, we won’t get the results. 😦 that’s cos we’re missing 1 more equation.

But we figured it out afterwards hahaha. THANKS FOR THE EFFORT THO~! “You should get in trouble”

Hi ya GIrL!! this is very tempting!! at least i can exercise my brain a bit!! its getting rusty you see…hehee.. but what i get is a = 433, b = 117, c = 0 and d =664.. i kinda get the ans by substituing all the equation to the last one..i didnt asssume that a = 0..hhmmmm… yeah this is kinda an impossible algebra ya~ hahahaha. cause got every different answer~~~ hehehe

Heyyyy girl! You tried it out too! LOL. See how it’s very weird cos one of the algebra becomes 0? The correct answer doesn’t have 0. a, b, c & d each is a number.

But don’t worry, it’s not ‘cos we’re stupid. It’s just because we’re missing an equation 😛

Hi Jess…hands got itchy while at work. my answer, a=-232, b=782, c=665, d=-1

No zeros… so is this right? Doesnt seem like there’s a missing equation =)

Hehe, nope. Actually, we made the equation because we needed to find the area of land after subdivision. So it’s very unlikely that area d of the land is -1 square metre big.

The missing equation we had was a/b = c/d. With that, you can solve everything 🙂
