when b = 10

1. 2(10 + 4) = 16
     28 
≠ 16                     FALSE

2. 2(10 + 2) = 40
     24 
≠  40                    FALSE

3. 3(10 – 2) = 24
          24 = 24                TRUE

4. 2(8 + 10) = 42
           36 
≠  42               FALSE


5. 3(10 – 4) = 20
        18 
≠  20                   FALSE

Answer is 
3. 3(b – 2) = 24
