Question

-5 = 6n + 7

n=

Answer 1

n = -2

Answer 2

Rearrange :

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-5-(6*n+7)=0
Step by step solution :
Step 1 :


Pulling out like terms :

1.1 Pull out like factors :

-12 - 6n = -6 • (n + 2)
Equation at the end of step 1 :

-6 • (n + 2) = 0

Step 2 :

Solve -6•(n+2) = 0

Equations which are never true :

2.1 Solve : -6 = 0

This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :

2.2 Solve : n+2 = 0

Subtract 2 from both sides of the equation :
n = -2
One solution was found :
n = -2

Answer 3

-5 = 6n + 7
-6n - 5 = 7
-6n = 12
n = -2
