Evaluate the following expression using the values given: Find 3x − y − 3z if x = −2, y = 1, and z = −2.

Respuesta :

The answer is -1. You can multiply 3 by -2 which is -6. Then y is, obviously, 1. 3z would equal -6 because 3 times -2 is -6. The final equation is: -6-1-(-6. -6 minus 1 1is -7. Then -7 minus -6 is -1 because a negative minus a negative will be a negative.
