=qx-3q

Solution for =qx-3q equation:

Simplifying
0 = qx + -3q

Reorder the terms:
0 = -3q + qx

Solving
0 = -3q + qx

Solving for variable 'q'.

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

Add '3q' to each side of the equation.
0 + 3q = -3q + 3q + qx
Remove the zero:
3q = -3q + 3q + qx

Combine like terms: -3q + 3q = 0
3q = 0 + qx
3q = qx

Add '-1qx' to each side of the equation.
3q + -1qx = qx + -1qx

Combine like terms: qx + -1qx = 0
3q + -1qx = 0

Factor out the Greatest Common Factor (GCF), 'q'.
q(3 + -1x) = 0

Subproblem 1
Set the factor 'q' equal to zero and attempt to solve:

Simplifying
q = 0

Solving
q = 0

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

Simplifying
q = 0
Subproblem 2
Set the factor '(3 + -1x)' equal to zero and attempt to solve:

Simplifying
3 + -1x = 0

Solving
3 + -1x = 0

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

Add '-3' to each side of the equation.
3 + -3 + -1x = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1x = 0 + -3
-1x = 0 + -3

Combine like terms: 0 + -3 = -3
-1x = -3

Add 'x' to each side of the equation.
-1x + x = -3 + x

Combine like terms: -1x + x = 0
0 = -3 + x

Simplifying
0 = -3 + x
