+ + = 30

= 10

+ + = 20

+ + 10 = 20

+ = 10

= 5

+ + = 13

+ + 5 = 13

+ = 8

= 4

So:

+ + = +( + + ) +

= 10 + ( 4 + 5 + 10 ) + 4

= 33

The answer is 33

#1

100 + x = 1700

x = 1700 - 100

x = 1600

= 40

#2

x x = 360

40 x x = 360

x = 360 : 40

x = 9

= 3

#3

x x = 480

40 x 3 x = 480

120 x = 480

= 480 : 120

= 4

#result

- += 40 - 4 + 3 = 39

So, the result is 39

#1

100 + x = 1700

x = 1700 - 100

x = 1600

= 40

#2

x x = 360

40 x x = 360

x = 360 : 40

x = 9

= 3

#3

x x = 480

40 x 3 x = 480

120 x = 480

= 480 : 120

= 4

#result
- + = 40 - 4 + 3 = 39
So, the result is 39

=(( 9 - 2 ) x 11 + 13 ) : ( 6 : 3 )

((9-2)*11+13)/(6/3)
