Let J be the number of books that Jonson has and let M be the number of books mandy has.

 

J-5=M+5

3(M-4)=(J+4)

 

now solve them simultaneously.  Can you do that?

What do you get for M and J?

X - number of books Johnson has

Y - number of books Mandy has

X - 5 = Y + 5 X = Y + 10

3(Y-4) = X + 4 3Y - X = 16

Substitute X in the second equation by (Y+10):

3Y - Y - 10 = 16

2Y = 26

Y = 13 books Mandy has

13 + 10 = 23 books Johnson has
