What are all of the steps to get 7(3x-1)-(x+5)

20x-12

Step-by-step explanation:

Given:

7(3x−1)−(x+5)

Step 1: Distribute the Negative Sign:

=7(3x−1)+−1(x+5)

=7(3x−1)+−1x+(−1)(5)

=7(3x−1)+−x+−5

Step 2: Distribute:

=(7)(3x)+(7)(−1)+−x+−5

=21x+−7+−x+−5

Step 3: Combine  

=21x+−7+−x+−5

=(21x+−x)+(−7+−5)

=20x+−12

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
