F(x)=3(0.7)x

Solution for F(x)=3(0.7)x equation:

Simplifying
F(x) = 3(0.7) * x

Multiply F * x
xF = 3(0.7) * x

Multiply 3 * 0.7
xF = 2.1x

Solving
xF = 2.1x

Solving for variable 'x'.

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

Add '-2.1x' to each side of the equation.
-2.1x + xF = 2.1x + -2.1x

Combine like terms: 2.1x + -2.1x = 0.0
-2.1x + xF = 0.0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-2.1 + 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 '(-2.1 + F)' equal to zero and attempt to solve:

Simplifying
-2.1 + F = 0

Solving
-2.1 + F = 0

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

Add '2.1' to each side of the equation.
-2.1 + 2.1 + F = 0 + 2.1

Combine like terms: -2.1 + 2.1 = 0.0
0.0 + F = 0 + 2.1
F = 0 + 2.1

Combine like terms: 0 + 2.1 = 2.1
F = 2.1

Add '-1F' to each side of the equation.
F + -1F = 2.1 + -1F

Combine like terms: F + -1F = 0
0 = 2.1 + -1F

Simplifying
0 = 2.1 + -1F
