Answer:

The answer is D. x=-1/2

Step-by-step explanation:

  • multiply the parantheses by 10 that'll give us 20x-40=100x
  • 2. move terms, that'll give us 20x-100x=40
  • 3. subtract 100x from 20x, that'll give us -80x=40
  • 4. divide both sides by -80, which is x=-1/2

Answer:

  • D. x = -1/2

Step-by-step explanation:

  • 10(2x - 4) = 100x

1. Divide both sides by 10.

  • 10/10 (2x - 4) = 100x/10
  • 2x - 4 = 10x

2. Add 4 to both sides.

  • 2x - 4 +4 = 10x + 4
  • 2x = 10x + 4

3. Subtract 10x from both sides.

  • 2x - 10x = 10x + 4 - 10x
  • -8x = 4

4. Divide both sides by -8.

  • -8x/-8 = 4/-8
  • x = -1/2

The answer is D.
