Solve x-1/2-y

$$\frac{ x-1 }{ 2 } -y$$

Evaluate

$$\frac{x-2y-1}{2}$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply y times \frac{2}{2}.

$$\frac{x-1}{2}-\frac{2y}{2}$$

Since \frac{x-1}{2} and \frac{2y}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{x-1-2y}{2}$$

Expand

$$\frac{x}{2}-y-\frac{1}{2}$$

Short Solution Steps
