7n=84fractions

Solution for 7n=84fractions equation:

Simplifying
7n = 84fractions

Solving
7n = 84acfinorst

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-84acfinorst' to each side of the equation.
-84acfinorst + 7n = 84acfinorst + -84acfinorst

Combine like terms: 84acfinorst + -84acfinorst = 0
-84acfinorst + 7n = 0

Factor out the Greatest Common Factor (GCF), '7n'.
7n(-12acfiorst + 1) = 0

Ignore the factor 7.
Subproblem 1
Set the factor 'n' equal to zero and attempt to solve:

Simplifying
n = 0

Solving
n = 0

Move all terms containing n to the left, all other terms to the right.

Simplifying
n = 0
Subproblem 2
Set the factor '(-12acfiorst + 1)' equal to zero and attempt to solve:

Simplifying
-12acfiorst + 1 = 0

Reorder the terms:
1 + -12acfiorst = 0

Solving
1 + -12acfiorst = 0

Move all terms containing n to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -12acfiorst = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -12acfiorst = 0 + -1
-12acfiorst = 0 + -1

Combine like terms: 0 + -1 = -1
-12acfiorst = -1

Add '12acfiorst' to each side of the equation.
-12acfiorst + 12acfiorst = -1 + 12acfiorst

Combine like terms: -12acfiorst + 12acfiorst = 0
0 = -1 + 12acfiorst

Simplifying
0 = -1 + 12acfiorst
