Chapter 1: Q 119. (page 39)

In the following exercises, evaluate each expression.
$y + (- 14)$ when
(a) $y = - 33$
(b) $y = 30$

Short Answer

Expert verified

(a) $- 47$

(b) 16

Step by step solution

Part (a). Step 1. Given Information:

The given expression is $y + (- 14)$ and the value of the variable is $y = - 33$ .

Part (a). Step 2. Substitute the value:

Substitute $- 33$ for $y$ into the given expression $y + (- 14)$ .

$- 33 + (- 14)$

Part (a). Step 3. Perform Subtraction:

Rewrite the obtained expression using the subtraction property, $a + (- b) = a - b$ .

$- 33 + (- 14) = - 33 - 14$

Subtract 14 from $- 33$ .

$- 33 - 14 = - 47$

Part (a). Step 4. Conclusion:

The value is $- 47$ .

Part (b). Step 1. Given Information:

The given expression is $y + (- 14)$ and the value of the variable is $y = 30$ .

Part (b). Step 2. Substitute the value:

Substitute 30 for $y$ into the given expression $y + (- 14)$ .

$30 + (- 14)$

Part (b). Step 3. Perform Subtraction:

Rewrite the obtained expression using the subtraction property, $a + (- b) = a - b$ .

$30 + (- 14) = 30 - 14$

Subtract 14 from 30.

$30 - 14 = 16$

Part (b). Step 4. Conclusion:

The value is 16.
