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?
+36916 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
