Answer:
n = -4
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
((6n - 2 • (4n + 7)) + 4) - -2 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-2n - 8 = -2 • (n + 4)
Equation at the end of step 3 :
-2 • (n + 4) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : n+4 = 0
Subtract 4 from both sides of the equation :
n = -4
One solution was found :
n = -4
