F(x)=4senx

Solution for F(x)=4senx equation:

Simplifying
F(x) = 4senx

Multiply F * x
xF = 4senx

Solving
xF = 4ensx

Solving for variable 'x'.

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

Add '-4ensx' to each side of the equation.
-4ensx + xF = 4ensx + -4ensx

Combine like terms: 4ensx + -4ensx = 0
-4ensx + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-4ens + F) = 0

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 '(-4ens + F)' equal to zero and attempt to solve:

Simplifying
-4ens + F = 0

Reorder the terms:
F + -4ens = 0

Solving
F + -4ens = 0

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

Add '-1F' to each side of the equation.
F + -1F + -4ens = 0 + -1F

Combine like terms: F + -1F = 0
0 + -4ens = 0 + -1F
-4ens = 0 + -1F
Remove the zero:
-4ens = -1F

Add '4ens' to each side of the equation.
-4ens + 4ens = -1F + 4ens

Combine like terms: -4ens + 4ens = 0
0 = -1F + 4ens

Simplifying
0 = -1F + 4ens
