Question

Evaluate the expression if x = 2, y = –3, and z = –10.
3 – |–z – 6y|

Answer 1

- 25

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
