Answer:

Issac's dog weighs 19 pounds

Step-by-step explanation:

Let x be Issac's dog's weight

  1. Translate the problem into an algebraic expression: x + (x + 12) = 50
  2. Simplify: 2x + 12 = 50
  3. Subtract 12 from each side, so it now looks like this: 2x = 38
  4. Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 19

I hope this helps!
