Math app level 61:

Update: they Now changed the level little bit:




Answer: 33

Solution (new):

Update: I have now removed old answer, And giving you the detailed solution to this level:

  • There are 3 variable so we need minimum 3 equations to get the value of each variable (A B and C)
  • Now we have only two equations, We can only find a relation between the variables.
  • So after using A=2n (for integral value), I Found the following relationship:

A=2n, B=3n-41, C=5n-74

Now for each value of n, they will satisfy both given equations, For example taking n=1


B=3×1-41= -38

C=5n-74= -69

So A+B-C

= 2+(-38)-(-69)



Now understood?????? Or still have a doubt?

Okey, Let us take another value of n, Let’s take n=0 (simplest)

A=0, B=-41, C=-74

A+B-C= 0-41+74=33 (again!)

try this with N=100 you will be surprised that answer is always 33

So those who are asking the exact value of A B and C, I want to tell you that there can not be any fixed value, you can take any value of A and solve for other two, but the answer will always be 33.

If there is any Doubt/discrepancy then please let me know in comments or you are unable to understand solution then I will surely help you.

    Dude why its so hard…
    I dont need “n” or something
    Because it so hard for me..hohoo
    I think it just

    a-4b+2c = 16
    2a+7b-5c = 83
    3a +3b-3c = 99
    a + b – c = 33
    So answer is 33

    It works :
    A = 30
    B = 4
    C = 3

    • August 2, 2019 at 4:48 pm

      Yes for N=15, It gives these values

  • July 22, 2019 at 3:23 am

    Its 33 i dont know how i tried many solutions

    No clue what you’re saying in the answer for the new answer could you put it differently?

    • June 22, 2019 at 6:12 am

      And give the actual value of each letter pls

      • June 23, 2019 at 9:04 pm

        a = 2 n, b = 3 n – 41, c = 5 n – 74,
        this is the value of each letter
        N can be anything here you can take zero
        so a=0, b=-41, c= -74

    You don’t need to know x=, y= or z =…

    1x -4y -1z = 5
    2x +7y -2z = 16
    3x +3y -3z = 21


    X + y -z = 7 zo you have the answer!

    • January 28, 2019 at 2:37 am

      yes, You are correct, thats what my equations say indirectly. But some users need to know everything that how to solve the question for each shape.

      • July 31, 2019 at 5:09 pm

        I just solved in another way..but no idea where A= 2n equation come from

        • July 31, 2019 at 7:03 pm

          Yes there must be another way, Can you share with all so that I can add it to post?

  • January 24, 2019 at 9:09 pm

    No, not at all. I cannot solve for this equation given the information. x comes out as 5 + 4y and y comes out as 6/15… And how would x – 4y = 5 jive with x + y = 7?
    I do not accept this answer, nor should anyone else given the thorough explanation on every other solution.

    • January 25, 2019 at 11:58 am

      are you serious, did you solve it correctly??
      y=2/5 and x=33/5 , these are the solution for x and y and hence x+y=7, i have another easy method for doing this, that i have added to post itself.

    • July 12, 2019 at 12:52 pm

      I tried solving it using the good ol’ trial and error and got a different answer.

      I came up with:
      A = 50
      B = 4
      C = 9

      50 – 4(4) + 2(9) = 16
      50 – 16 + 18 = 16

      2(50) + 7(4) – 5(9) =83
      100 + 28 – 45 = 83

      50 + 4 – 9 = 45

      It all checks out. But I suppose that is the wrong way of solving it?

      • July 12, 2019 at 3:44 pm

        Not 16

        • July 17, 2019 at 5:14 am

          How come? MDAS does not apply?

          • July 17, 2019 at 10:15 am

            If the expression was 50-(16+18) then it would have been correct
