1)  a+b+c+d+e+f+g+h+i+j+k+l = 24.05

2)  (a+b+c+d+e+f) - (g+h+i+j+k+l) = 6.05

3)  9(a+b+c+d+e+f) / (g+h+i+j+k+l) = 15.05

 

4)  (a+b+c+g+h+j) - (d+e+f+i+j+l) = 2.95

5)  (a+c+e+g+i+k) - (b+d+f+h+i+j) = 1.95

6)  2(d+e+f+i+j+l) - (a+b+c+g+h+j) = 7.6

7)  abc + def + ghi + jkl = 40.978

8)  (abc + ghi) - (def - jkl) = 19.642

9)  ab + cd + ef + gh + ij + kl = 28.48

10)  (ab + ef + ij) - (cd + gh + kl) = 12.52

11)  (a+b)*(c+d) + (e+f)*(g+h) + (i+j)*(k+l) = 48.45

12)  (a+b)*(c+d) - (e+f)*(g+h) - (i+j)*(k+l) = 8.55

 

a=? b=? c=? d=? e=? f=? g=? h=? i=? j=? k=? l=?

 

Let     x = a+b+c+d+e+f           and   y = g+h+i+j+k+l

x+y=24.05   From (1)

x-y=6.05      From (2)

add

2x=30.1

x=15.05

y=24.05-15.05 = 9

so

lets look at (3)

9x/y = 9*15.05/9 = 15.05     so (3) is true and it does not help solve anything.

 

So we have exhausted all the clues from  lines 1,2 and 3 and we have discovered that:

 

a+b+c+d+e+f = 15.05      and          g+h+i+j+k+l = 9

 

My interest has now wained, maybe I will come back to it later.    :)

I didn't create the design, so credit actually goes to ACII Text Art.

-2x2-5x=-50

 

Hello Guest!

 

          \(-2x^2-5x=-50\)         [ both sides + 50

\(-2x^2-5x+50=0\)               [ : (-2)  

    \(x^2+\frac{5}{2}x-25=0\)

              p          q

\(x=-\frac{p}{2}\pm\sqrt{\frac{p^2}{4}-q}\)                [ p,q transfer

\(x=-\frac{5}{4}\pm\sqrt{\frac{25}{16}+25}\)             [ calculate root

\(x=-\frac{5}{4}\pm\sqrt{26.5625}=-1.25\pm5.15388203202\)

\(x_1=3.90388203202\\ x_2=-6.40388203202\)
