Answer:
Issac's dog weighs 19 pounds
Step-by-step explanation:
Let x be Issac's dog's weight
- Translate the problem into an algebraic expression: x + (x + 12) = 50
- Simplify: 2x + 12 = 50
- Subtract 12 from each side, so it now looks like this: 2x = 38
- 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!
