Question

The number of points scored by the home team at a basketball game is represented by (x+6). The number of points scored by the visiting team is represented by (3x −6). Write 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 5.

Answer 1

2

Explanation:

(x + 6) - (3x - 6) Remove the brackets.

x + 6 - 3x + 6 Collect like terms

Difference in points = 12 - 2x

If x = 5 then

Difference in points = 12 - 2*5

Difference in points = 12 - 10

Difference in points = 2
