Note last line has 1 spanner, 1 man holding 2 spanners and wearing 1 hat and holding 1 hat, and 1 hat

We need to obey Maths rules when performing multiple operations of addition, subtraction, division and multiplication (BODMAS)

1st Line 

(5 x 2) + (5 x 2) + (5 x 2) = 30     6 spanners = 30 so  1 Spanner = 5

2nd Line

Man + Man + 2 Spanners = 20

Man + Man + 10 = 20      so 2 men = 10

5 + 5 + (5 x 2) = 20     Man = 5

3rd line

2 Hats + 2Hats +Man= 13

as 1 man =5 then 4 hats =8, so 1 hat =2

(2 x 2) + (2 x 2) + 5 = 13     Hat = 2

4th line

Spanner + (Man+Hat+Hat+2 spanners) x Hat = ?

5 + (5+2+2+5+5) X 2

5 + 19 x 2

USE BODMAS  so multiply first 19 X 2 = 38  

5+38=43

Answer = 43
