Question

$$(x+y)/2-7$$

Evaluate

$\frac{x+y-14}{2}$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply $7$ times $\frac{2}{2}$.

$$\frac{x+y}{2}-\frac{7\times 2}{2}$$

Since $\frac{x+y}{2}$ and $\frac{7\times 2}{2}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{x+y-7\times 2}{2}$$

Do the multiplications in $x+y-7\times 2$.

$$\frac{x+y-14}{2}$$
