You should be able to solve this,
You should be able to solve this
Left to right, top to bottom:
7/2, 9/2, 19/2, 7/2
4 equations, 4 unknowns. Assuming there is a solution to this system of equations then yes it is a simple exercise in basic math to solve.
This is correct
This is the method
Hope you understand your homework now OP
>Under-determined system
>On Veeky Forums
If we're restricted to integers then there's no solution. Otherwise there's an infinite number of solutions.
Not really fucking Fapen stole my extra point because he used decimals
You should definitely be able to solve this
31, right?
42
Correct
My sytem works to, you cunt!
1. x2
2. +11
3. x2
4. +11
...
112
>1*2 = 1
Literally what. Please explain.
I am able to solve it but too lazy to actually do it.
I don't hate kurisuTIIINA as a character but every time I see her on this centrafrican mask engraving picture book I get an aneurysm
x+y=8
x+z=13
y+w=8
z-w=6
y+z=14
x-y=-1
2x=7
x=3.5
y=8-3.5=4.5
z=14-4.5=9.5
w=8-4.5=3.5
you didn't show how you got 2x=7
Add the 2 previous terms right above 2x=7
lol, you are right :D
And that, my son, is why you fail.
38
poor little brainlet
left base 7
right base 3
answer is 112
3.5+4.5=8
+ +
9.5-3.5=6
= =
13 8
I did brute force but in retrospect its just basic math and I'm just a retard
x+y=8
x+z=13
z-x=6
Solving for z first because I fucking feel like it
x+z=13
z-x=6
Combine them
2z=19
z=9.5
Now solve for x
9.5+x=13
x=3.5
Now y
3.5+y=8
y=4.5
It only took me like a minute longer for brute force though.
20 = 20 by definition
42
01=10*0+(0+1)
10=10*2+(1+0)
11=10*2+(1+1)
20=10*4+(2+0)=42
xy=10*2x+(x+y)
Would you care to show 2 of these?
This solution literally makes no sense.
>his solution doesn't work for numbers of more than two digits
lol
see
It's in base 21 you retard
The solution is trivial and left to the reader as an exercise.

If the exponential value isn't going to change it should work like this.
Sorry but why did you need x-y=-1 and how did you get it? From y+z=14 I was able to find 2x=7 easily and the rest is done, but why did you need x-y=-1?
