Solve total for Harry.

Question

Jack and Harry have 102 marbles. Harry has 5 times more than Jack. How many does Harry have?

Answer 1

What are the unknowns? The amount of marbles that Jack has and the number of marbles that Harry has. Let x = the number of marbles Jack has. Then Harry has 5x marbles. Together they have 102 marbles. Hence, we can write the following linear equation:

 

x + 5x = 102

 

Can you solve this for x?
