Hi Luke,
We can answer this question through the following steps:
Step One: Since we know that the total number of games is 49, we can create the Let Statements
Let x= the number of games Preston has
Let x+11=the number of games Horatio has
Step Two: Create an equation
Total Number of Games = (the number of games Preston has)+(the number of games Horatio has)
49=x+(x+11) Distribute
49=x+x+11 Combine like terms
49=2x+11 Subtract 11 from both sides
49-11=2x
38=2x Divide both sides by 2
19=x
∴Preston has 19 games and Horatio has 30 games because 19+11=30.
Best,
