$y = 1 (\frac{5}{2}) + 2$

Multiply $\frac{5}{2}$ by $1$ .

$y = \frac{5}{2} + 2$

To write $2$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$y = \frac{5}{2} + 2 \cdot \frac{2}{2}$

Combine $2$ and $\frac{2}{2}$ .

$y = \frac{5}{2} + \frac{2 \cdot 2}{2}$

Combine the numerators over the common denominator.

$y = \frac{5 + 2 \cdot 2}{2}$

Simplify the numerator.

Multiply $2$ by $2$ .

$y = \frac{5 + 4}{2}$

Add $5$ and $4$ .

$y = 0 (\frac{5}{2}) + 2$

Multiply $0$ by $\frac{5}{2}$ .

$y = 0 + 2$

Add $0$ and $2$ .

$y = 2$

Step 7

Substitute $1$ for $x$ and find the result for $y$ .

$y = - \frac{5}{2} \cdot 1 + 2$

Step 8

$y = - \frac{5}{2} \cdot 1 + 2$

Simplify $- \frac{5}{2} \cdot 1 + 2$ .

Multiply $- 1$ by $1$ .

$y = - \frac{5}{2} + 2$

To write $2$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$y = - \frac{5}{2} + 2 \cdot \frac{2}{2}$

Combine $2$ and $\frac{2}{2}$ .

$y = - \frac{5}{2} + \frac{2 \cdot 2}{2}$

Combine the numerators over the common denominator.

$y = \frac{- 5 + 2 \cdot 2}{2}$

Simplify the numerator.

Multiply $2$ by $2$ .

$y = \frac{- 5 + 4}{2}$

Add $- 5$ and $4$ .

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

Move the negative in front of the fraction.
