Question 1016975: in this Verbal excersice I have to present a linear algebraic equation
mark and don are planning to sell each of their marble collections at a garage sale. if don has 1 more than 3 times the number of marbles mark has, how many does each boy have to sell if the total number of marbles 113? Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! let x be the number of marbles that Mark has and y be the number of marbles Don has, then
1) x + y = 113
2) y = 3x + 1
:
substitute for y in equation 1 using equation 2
:
x + (3x + 1) = 113
:
4x = 112
:
x = 28
:
Mark has 28 marbles and Don has 85 marbles
