Answer:

First question: x = 20

Step-by-step explanation:

  1. Write it out: (5x + 17) + (2x + 23) = 180
  2. Combine like terms: 5x + 2x = 7x, 17 + 23 = 40
  3. Put them back together: 7x + 40 = 180
  4. Subtract 40 from each side, so it now looks like this: 7x = 140
  5. Divide each side by 7, so it now looks like this: x = 20

I forgot to do the second question! I'm sorry! I hope this helps anyway!
