Question 1065412: Use the information to find a linear algebraic equation model that can be used to answer the question.
Mark and Don are planning to sell each of their marble collections at a garage sale. If Don had 2 more than 5 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles are is 92?
Don ______ marbles
Mark ______ marbles

You can put this solution on YOUR website!
D=2%2B5M
and
D%2BM=92
Substituting,
%282%2B5M%29%2BM=92
6M%2B2=92
6M=90
M=15
Now that you know Mark has 15 marbles, use either equation to solve for D, the number of Don's marbles.
