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

$$+ \frac { - y } { 2 } + 2 ) ( - \frac { - x } { 2 } - \frac { y } { 7 }$$

Evaluate

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

Short Solution Steps

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

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

Since \frac{-y}{2} and \frac{2\times 2}{2} have the same denominator, add them by adding their numerators.

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

Do the multiplications in -y+2\times 2.

$$\frac{-y+4}{2}$$

Factor

$$\frac{4-y}{2}$$

Solution Steps

Factor out \frac{1}{2}.

$$\frac{-y+4}{2}$$
