Chapter 1.1, Problem 47HP

To determine

To find: an algebraic expression for $x,y$ and $z$ to get the value as 10.

Answer to Problem 47HP

An algebraic expression may be $xy+z$ .

Explanation of Solution

Given information:

The value of $x,y$ and $z$ is given as

  $x=-2,y=-3$ and $z=4$

Calculation:

Now, value of the expression is 10.

10 can be written as shown:

  $\begin{array}{c}10=6+4\\ =\left(-3\right)\left(-2\right)+4\\ =xy+z\left[x=-2,y=-3,z=4\right]\end{array}$

Hence, an algebraic expression may be $xy+z$ .
