Deez has 7 times as many marbles as kut. If Deez gives 12 marbles to kut, the two children will have exactly the same amount. How many marbles do they have altogether?

d = 7k

 

then

 

d-12 = k + 12     sub in the top equation

 

7k   -12    = k + 12

6k = 24

k = 4      initially     then k got 12 more = 16    and they both had the same amount for a total = 32 marbles
