Answer:
The heavier boy would weigh 86 pounds.
Explanation:
Let's say boy=b, the equation would be:
2b+34=138
This is because the boys would weigh the same, with an exception of 34 pounds.
But we need to find just one person's weight. So bring 34 to the other side:
2b=138-34
Solve:
2b=104
Now, we need to find b:
b=52
So one boy would weigh 52, and the other would weigh 52+34, which is 86.
The heavier boy would weigh 86 pounds.
Happy learning!
