Answer: x + x + 12 = 36, 12 pounds
Step-by-Step Explanation:
Let Joe’s dog’s weight be ‘x’ pounds
Peter’s dog’s weight be ‘x + 12’ pounds
Both dogs weigh 36 pounds together.
Therefore,
x + x + 12 = 36
2x + 12 = 36
2x = 36 - 12
2x = 24
x = 24/2
=> x = 12
Joe’s Dog’s Weight = x => 12
Peter’s Dog’s Weight = x + 12 => 24
