(a) Simplify the expression: (4x - 6) - (x + 5) (b) The number of points scored in 3 games are 4x, x + 6, and 5x - 2. Find the total number of points scored in these 3 games (Hint: total = add).

a) 3x - 11

b) 10x + 4

Step-by-step explanation:

a) The negative sign before the (x+5) means to subtract those values. Reverse the signs. Then combine like terms:

4x –6 –x –5. 4x–x–6–5

3x –11

b) Put all the x terms together.

Put all the integers together.

Add. Adding a negative is the same as subtracting.

4x+x+5x = 10x

+6-2 = 4

Combine them:

10x + 4
