Answer:

x = -2

Step-by-step explanation:

Let x be the number:

  1. 5(x + 8) = 30
  2. Apply the distributed property, so it now looks like this: 5x + 40 = 30
  3. Subtract 40 from each side, so it now looks like this: 5x = -10
  4. Divide each side by 5 to cancel out the 5 next to x. It should now look like this: x = -2

I hope this helps!
