The expression that represents the total number of points you have now is 2x + 17
Solution:
Given that you earn (4x+12) points after completing x level of a video game
And then lose (2x – 5) points
Need to determine expression which represents the total
The total after completing “x” levels is obtained by finding the difference between points earned and point lose
Total = Point earned - Point lose
= (4x + 12) – (2x – 5)
= 4x + 12 – 2x + 5
= 4x – 2x + 12 + 5
=> Total = 2x + 17
Hence expression which represents total points is 2x + 17
