HELP

Answer 1

8x + 1 = 1; Step 2: 8x = 0

8x − 9 = 1; Step 2: 8x = 10

15x − 20 = 1; Step 2: 15x = 21

15x − 4 = 1; Step 2: 15x = 5

C, Sorry i'm kinda late...

Answer:

  (C)  Step 1: 15x − 20 = 1; Step 2: 15x = 21

Step-by-step explanation:

The first step is to eliminate the parentheses, using the distributive property.

  5(3x − 4) = 1

  15x -20 = 1

The second step is to add 20 to both sides of the equation.

  15x = 21

This pair of steps is shown in the 3rd choice.

Comment on the answers

The distributive property seems to be applied incorrectly a lot of the time. Here, you can choose the correct answer by looking at the result of properly applying the distributive property: 5(3x-4) = 15x-20. Only the correct choice has this as the first step.
