If it's not what You are looking for type in the equation solver your own equation and let us solve it.

Simplifying f(x) = 2x + 5 Multiply f * x fx = 2x + 5 Reorder the terms: fx = 5 + 2x Solving fx = 5 + 2x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = 5x^{-1}+ 2 Simplifying f = 5x^{-1}+ 2 Reorder the terms: f = 2 + 5x^{-1}
