F(x)=7(0.9)x

Solution for F(x)=7(0.9)x equation:

Simplifying
F(x) = 7(0.9) * x

Multiply F * x
xF = 7(0.9) * x

Multiply 7 * 0.9
xF = 6.3x

Solving
xF = 6.3x

Solving for variable 'x'.

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

Add '-6.3x' to each side of the equation.
-6.3x + xF = 6.3x + -6.3x

Combine like terms: 6.3x + -6.3x = 0.0
-6.3x + xF = 0.0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-6.3 + F) = 0.0

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 '(-6.3 + F)' equal to zero and attempt to solve:

Simplifying
-6.3 + F = 0

Solving
-6.3 + F = 0

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

Add '6.3' to each side of the equation.
-6.3 + 6.3 + F = 0 + 6.3

Combine like terms: -6.3 + 6.3 = 0.0
0.0 + F = 0 + 6.3
F = 0 + 6.3

Combine like terms: 0 + 6.3 = 6.3
F = 6.3

Add '-1F' to each side of the equation.
F + -1F = 6.3 + -1F

Combine like terms: F + -1F = 0
0 = 6.3 + -1F

Simplifying
0 = 6.3 + -1F
