Solve +a/2-6

$$+ \frac { a } { 2 } - 6$$

Evaluate

$$\frac{a}{2}-6$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply 6 times \frac{2}{2}.

$$\frac{a}{2}-\frac{6\times 2}{2}$$

Since \frac{a}{2} and \frac{6\times 2}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{a-6\times 2}{2}$$

Do the multiplications in a-6\times 2.

$$\frac{a-12}{2}$$

Factor

$$\frac{a-12}{2}$$

Solution Steps

Factor out \frac{1}{2}.

$$\frac{a-12}{2}$$
