Xl=2fl

Solution for Xl=2fl equation:

Simplifying
Xl = 2fl

Solving
lX = 2fl

Solving for variable 'l'.

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

Add '-2fl' to each side of the equation.
-2fl + lX = 2fl + -2fl

Combine like terms: 2fl + -2fl = 0
-2fl + lX = 0

Factor out the Greatest Common Factor (GCF), 'l'.
l(-2f + X) = 0

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

Simplifying
l = 0

Solving
l = 0

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

Simplifying
l = 0
Subproblem 2
Set the factor '(-2f + X)' equal to zero and attempt to solve:

Simplifying
-2f + X = 0

Reorder the terms:
X + -2f = 0

Solving
X + -2f = 0

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

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

Combine like terms: X + -1X = 0
0 + -2f = 0 + -1X
-2f = 0 + -1X
Remove the zero:
-2f = -1X

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

Combine like terms: -2f + 2f = 0
0 = -1X + 2f

Simplifying
0 = -1X + 2f
