n = 3
Step-by-step explanation:
Step 1 :
1
Simplify —
2
Equation at the end of step 1 :
1
(— • (2n + 4)) - 5 = 0
2
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
2n + 4 = 2 • (n + 2)
Equation at the end of step 3 :
(n + 2) - 5 = 0
Step 4 :
Equation at the end of step 4 :
n - 3 = 0
Step 5 :
Solving a Single Variable Equation :
5.1 Solve : n-3 = 0
Add 3 to both sides of the equation :
n = 3
One solution was found :
n = 3
