Question

Answer

This is a Before After question.

   Before  Transfer  After    
Jump 7u -18 7u -18  
Run 4u +18 4u + 18  
Total 11u      

7u – 18 = 4u + 18

7u – 4u = 18 + 18

3u = 18

1u = 18 ÷3 = 6

11u = 11 × 6 =  66

Try your other problems using this method.

It is easy, but need more practices.
