Evaluate the expression if x = 2, y = - 3, and z = - 10.

3 - |-z - 6y|

- 25

Step-by-step explanation:

The absolute value always returns a positive value, that is

| - a | = | a | = a

Given

3 - | - z - 6y |

Substitute y = - 3 and z = - 10 into the expression

= 3 - | - ( - 10) - 6 ( - 3) |

= 3 - | 10 + 18 |

= 3 - | 28 |

= 3 - 28

= - 25
