12u-9u=6whatisu

Solution for 12u-9u=6whatisu equation:

Simplifying
12u + -9u = 6whatisu

Combine like terms: 12u + -9u = 3u
3u = 6whatisu

Solving
3u = 6ahistuw

Solving for variable 'u'.

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

Add '-6ahistuw' to each side of the equation.
-6ahistuw + 3u = 6ahistuw + -6ahistuw

Combine like terms: 6ahistuw + -6ahistuw = 0
-6ahistuw + 3u = 0

Factor out the Greatest Common Factor (GCF), '3u'.
3u(-2ahistw + 1) = 0

Ignore the factor 3.
Subproblem 1
Set the factor 'u' equal to zero and attempt to solve:

Simplifying
u = 0

Solving
u = 0

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

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

Simplifying
-2ahistw + 1 = 0

Reorder the terms:
1 + -2ahistw = 0

Solving
1 + -2ahistw = 0

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

Add '-1' to each side of the equation.
1 + -1 + -2ahistw = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -2ahistw = 0 + -1
-2ahistw = 0 + -1

Combine like terms: 0 + -1 = -1
-2ahistw = -1

Add '2ahistw' to each side of the equation.
-2ahistw + 2ahistw = -1 + 2ahistw

Combine like terms: -2ahistw + 2ahistw = 0
0 = -1 + 2ahistw

Simplifying
0 = -1 + 2ahistw
