Solution for -2x=f(x+3) equation:


Simplifying
-2x = f(x + 3)

Reorder the terms:
-2x = f(3 + x)
-2x = (3 * f + x * f)
-2x = (3f + fx)

Solving
-2x = 3f + fx

Solving for variable 'x'.

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

Add '-1fx' to each side of the equation.
-1fx + -2x = 3f + fx + -1fx

Combine like terms: fx + -1fx = 0
-1fx + -2x = 3f + 0
-1fx + -2x = 3f

Reorder the terms:
-3f + -1fx + -2x = 3f + -3f

Combine like terms: 3f + -3f = 0
-3f + -1fx + -2x = 0

Factor out the Greatest Common Factor (GCF), '-1'.
-1(3f + fx + 2x) = 0

Ignore the factor -1.

Subproblem 1
