F(x)=7cos(x)

Solution for F(x)=7cos(x) equation:

Simplifying
F(x) = 7cos(x)

Multiply F * x
xF = 7cos(x)

Multiply cos * x
xF = 7cosx

Solving
xF = 7cosx

Solving for variable 'x'.

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

Add '-7cosx' to each side of the equation.
-7cosx + xF = 7cosx + -7cosx

Combine like terms: 7cosx + -7cosx = 0
-7cosx + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-7cos + 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 '(-7cos + F)' equal to zero and attempt to solve:

Simplifying
-7cos + F = 0

Reorder the terms:
F + -7cos = 0

Solving
F + -7cos = 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 + -7cos = 0 + -1F

Combine like terms: F + -1F = 0
0 + -7cos = 0 + -1F
-7cos = 0 + -1F
Remove the zero:
-7cos = -1F

Add '7cos' to each side of the equation.
-7cos + 7cos = -1F + 7cos

Combine like terms: -7cos + 7cos = 0
0 = -1F + 7cos

Simplifying
0 = -1F + 7cos
