Solve for x f(1)=2x-1

$f (1) = 2 x - 1$

Rewrite the equation as $2 x - 1 = f (1)$ .

$2 x - 1 = f (1)$

Multiply $f$ by $1$ .

$2 x - 1 = f$

Add $1$ to both sides of the equation.

$2 x = f + 1$

Divide each term in $2 x = f + 1$ by $2$ and simplify.

Divide each term in $2 x = f + 1$ by $2$ .

$\frac{2 x}{2} = \frac{f}{2} + \frac{1}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 x}{2} = \frac{f}{2} + \frac{1}{2}$

Divide $x$ by $1$ .

$x = \frac{f}{2} + \frac{1}{2}$
