Chapter 2: Q76. (page 88)

REASONING Determine the value for each statement below.
a. If $x - 7 = 14$ , what is the value of $x - 2$ ?
b. If $t + 8 = - 12$ , what is the value of $t + 1$ ?

Short Answer

Expert verified

The value of $x - 2$ is 19.
The value of $t + 1$ is $- 19$ .

Step by step solution

Part a. Step 1. Write the given information.

The given equation is: $x - 7 = 14$

Part a. Step 2. Calculation.

Consider the given equation,

$\begin{array}{l} x - 7 = 14 \\ x = 14 + 7 \\ x = 21 \end{array}$

Part a. Step 3. Computing the value of required expression.

Substitute $x = 21$ in $x - 2$ , we get

$21 - 2 = 19$

So, The value of $x - 2$ is 19.

Part b. Step 1. Write the given information.

The given equation is: $t + 8 = - 12$

Part b. Step 2. Calculation.

Consider the given equation,

$\begin{array}{l} t + 8 = - 12 \\ t = - 12 - 8 \\ t = - 20 \end{array}$

Part b. Step 3. Computing the value of required expression.

Substitute $t = - 20$ in $t + 1$ , we get

$- 20 + 1 = - 19$

So, the value of $t + 1$ is $- 19$ .
