Exercise 59 Page 351

Substitute the given values into the equation and then simplify.

False

Practice makes perfect

We can determine whether the given statement is true or false for x= 8, y= 2, and z= 3 by substituting the given values into the equation and simplifying using the order of operations.

z(x-y)\stackrel{?}=13

SubstituteValues

Substitute values

{\color{#A800DD}{3}}({\color{#0000FF}{8}}-{\color{#009600}{2}})\stackrel{?}=13

SubTerm

Subtract term

3(6)\stackrel{?}=13

Multiply

18 ? =13 *

Therefore, the statement is false for x=8, y=2, and z=3.
