    $\begingroup$ Do we assume that 2 blue/green balloons = 2x1 balloon? That can be a 4th and 5th independant symbol $\endgroup$ – Saeïdryl Jun 26 '18 at 7:45
  • $\begingroup$ On the second row, the two sets of green are different. Is this significant? $\endgroup$ – Kami Jun 26 '18 at 10:02

First line: 3 red balloons = 30 -> red = 10.
Second line: 10 + 4 green balloons = 18 -> green = 2.
Third line: 4 - 2 blue balloons = 2 -> blue = 1.
Final answer: 1 + 10 x 2 = 21.

    $\begingroup$ I don't think that matters; if it does, there is not enough information to solve the equation. $\endgroup$ – Glorfindel Jun 26 '18 at 7:47

Let's replace baloons by variables because I prefer math than party

  • red baloon = x
  • green baloon = y
  • blue baloon = z

we got :

  • x + x + x = 30
  • x + 2y + 2y = 18
  • 2y - 2z = 2
  • z + x * y = ??

given the first equation:

3x = 30
x = 10

the second equation is now:

10 + 4y = 18
4y = 8
y = 2

the third equation is know:

4 - 2z = 2
-2z = -2
z = 1

So, the last equation is:

z + x * y = ??
1 + 10 * 2 = ??
1 + 20 = ??

the solution is

21

    $\begingroup$ @Jawhari that's the exact reason why I like variable-based equations but hate ballon-based, fruits-based or whatever-based equations... $\endgroup$ – Kepotx Jun 26 '18 at 7:46

    $\begingroup$ also, the two green baloons have not the same colour, does that means it's two different baloons? $\endgroup$ – Kepotx Jun 26 '18 at 7:47

Suppose red balloon = x

So, x + x + x = 30
=> x = 10

Suppose green balloon = y

So, x + 2*y + 2*y = 18
=> 10 + 4*y = 18
=> y = 2

Suppose blue balloon = z

So, 2*y - 2*z = 2
=> 4 - 2z = 2
=> z = 1

Now,

z + x * y = 1 + 10 * 2 = 1 + 20 = 21
