Final answer:
The expression to find how many more runs the home team scored than the visiting team is (x + 7) - (3x - 7). If the value of x is 6, the home team scored 2 more runs than the visiting team.
Step-by-step explanation:
To find how many more runs the home team scored than the visiting team, we need to subtract the number of runs scored by the visiting team from the number of runs scored by the home team. The expression for this is (x + 7) - (3x - 7). Let's simplify this expression:
Distribute the negative sign to the second expression: (x + 7) - 3x + 7
Combine like terms: x - 3x + 7 + 7 = -2x + 14
If we substitute x with 6, we can evaluate the expression: -2(6) + 14 = -12 + 14 = 2
Therefore, if the value of x is 6, the home team scored 2 more runs than the visiting team.
