Well it’s obviously C(8) because 8+8=16

Pulling out like terms :

3.1 Pull out like factors :

24 - 8x = -8 • (x - 3)

Equation at the end of step 3 : -8 • (x - 3) = 0 Step 4 :Equations which are never true :

4.1 Solve : -8 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : x-3 = 0

Add 3 to both sides of the equation :
x = 3

One solution was found : x = 2
