4x(3-y)=0

Solution for 4x(3-y)=0 equation:

Simplifying
4x(3 + -1y) = 0
(3 * 4x + -1y * 4x) = 0
(12x + -4xy) = 0

Solving
12x + -4xy = 0

Solving for variable 'x'.

Ignore the factor 4.
Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:

Simplifying
x = 0

Solving
x = 0

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

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

Simplifying
3 + -1y = 0

Solving
3 + -1y = 0

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

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

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

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

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

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

Simplifying
0 = -3 + y
