Given :
Runs scored by home team is (x + 7).
Runs scored by visiting team is (3x - 7).
To Find :
An expression to find how many more runs the home team scored than the visiting team. Then evaluate the expression if the value of x is 6.
Solution :
Let, number of more runs the home team scored than the visiting team is R.
R = (x + 7) - (3x - 7)
R = 14 - 2x
Now, putting value of x = 6 in above equation, we get :
R = 14 - 2( 6 )
R = 2
Hence, this is the required solution.
