Can someone please help me with this problem!!

Step-by-step explanation:

the bat is 12. the pumpkin is 5. and the weird looking thing is 14

14 plus 14 plus 12 is 40

12 minus 5 is 7

5 plus 14 is 19

14 minus 5 plus 12 is 21

  21

Step-by-step explanation:

Green bat:   x

Purple bat:   y

  Pumpkin:   z

Given:

  2x + y = 40

  y - z = 7                ===>      y = 7 + z

  z + x = 19             ===>       z = 19 - x

Substitution to find green bat x:

  2x + y = 40

  2x + (7 + z) = 40

  2x + 7 + z = 40

  2x + 7 + (19 - x) = 40

  2x + 7 + 19 - x = 40

  x + 26 = 40

  green bat:  x = 14

Substitution to find pumpkin z:

  z + x = 19

  z + (14) = 19

  z + 14 = 19

  pumpkin:  z = 5

Substitution to find purple bat y:

  y - z = 7

  y - (5) = 7

  y - 5 = 7

  purple bat:  y = 12

Solve for x - z + y:

  14 - 5 + 12 = 21

this is answer of 144 cubic meters

answer: you need to organize this better it does not make sense.
