x - bear

y - bus
z - hat

3(x+z)=21
x+z = 21/3=7

2(x+y)+7=19
2(x+y)=12
x+y=6

z + 6 +7 = 15
z = 15-13=2

x= 7-2=5
y=6-5=1

x + 2z *1 = 5+ 4*1=9

I did not notice the multiplication sign, so got a 10.botan

And I - 19.

Now -15.

Thank you all

From the first example we find the bear with the hat
21:3=7
From the second example we find a bus with a bear, but without the hat
(19 -7):2=6
the third example we find the hat
15 -7-6=2
last example
Bear without a hat 7-2=5
Bus no bear 6-5=1
Consider that the two hats
5+4*1=9

Express:bear-x;bus-y, cap-z.Equation: 3x+3z=21 ; 3x +2y +z =19; 2x +y +2z = 15.From the 1st equation: 3x + 3z =21 , x+z = 7. From the 2nd of ur-tion: 3x + 2y +z = 19. Otherwise:2x + 2y +x +z = 19 . x + y = 6. From the 3rd :2x + y +2z = 15 ; Otherwise: (x +z) + (x + y) +z =15 ,7 +6 + z =15 , z=2. Substitute in the last ur-tion: x + 2y * z = ?. x =7 - 2 =5,y=6 -5=1. It turns out: 5 + 2 *2 = 9. Something like that.book
